Summary
The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.

Summary
An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems. This allowed a client with any domain validated certificate signed by a system-trusted root CA (as opposed to one signed by the configured CA root certificate) to authenticate.

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade limit access to the host to trusted users. Limit access to host volumes to trusted containers.

Summary
Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in `dockerd` and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The `overlay` network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with the VXLAN metadata, including a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the `u32` iptables extension provided by the `xt_u32` kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
An iptables rule designates outgoing VXLAN datagrams with a VNI that corresponds to an encrypted overlay network for IPsec encapsulation.
Encrypted overlay networks on affected platforms silently transmit unencrypted data. As a result, `overlay` networks may appear to be functional, passing traffic as expected, but without any of the expected confidentiality or data integrity guarantees.
It is possible for an attacker sitting in a trusted position on the network to read all of the application traffic that is moving across the overlay network, resulting in unexpected secrets or user data disclosure. Thus, because many database protocols, internal APIs, etc. are not protected by a second layer of encryption, a user may use Swarm encrypted overlay networks to provide confidentiality, which due to this vulnerability this is no longer guaranteed.
Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. Close the VXLAN port (by default, UDP port 4789) to outgoing traffic at the Internet boundary in order to prevent unintentionally leaking unencrypted traffic over the Internet, and/or ensure that the `xt_u32` kernel module is available on all nodes of the Swarm cluster.

Summary
A flaw was found in cri-o, where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.

Summary
Moby) is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in `dockerd` and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The `overlay` network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with the VXLAN metadata, including a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the `u32` iptables extension provided by the `xt_u32` kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
The `overlay` driver dynamically and lazily defines the kernel configuration for the VXLAN network on each node as containers are attached and detached. Routes and encryption parameters are only defined for destination nodes that participate in the network. The iptables rules that prevent encrypted overlay networks from accepting unencrypted packets are not created until a peer is available with which to communicate.
Encrypted overlay networks silently accept cleartext VXLAN datagrams that are tagged with the VNI of an encrypted overlay network. As a result, it is possible to inject arbitrary Ethernet frames into the encrypted overlay network by encapsulating them in VXLAN datagrams. The implications of this can be quite dire, and GHSA-vwm3-crmr-xfxw should be referenced for a deeper exploration.
Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. In multi-node clusters, deploy a global ‘pause’ container for each encrypted overlay network, on every node. For a single-node cluster, do not use overlay networks of any sort. Bridge networks provide the same connectivity on a single node and have no multi-node features. The Swarm ingress feature is implemented using an overlay network, but can be disabled by publishing ports in `host` mode instead of `ingress` mode (allowing the use of an external load balancer), and removing the `ingress` network. If encrypted overlay networks are in exclusive use, block UDP port 4789 from traffic that has not been validated by IPSec.

Summary
Moby is an open-source project created by Docker to enable software containerization. The classic builder cache system is prone to cache poisoning if the image is built FROM scratch. Also, changes to some instructions (most important being HEALTHCHECK and ONBUILD) would not cause a cache miss. An attacker with the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially crafted image that would be considered as a valid cache candidate for some build steps. 23.0+ users are only affected if they explicitly opted out of Buildkit (DOCKER_BUILDKIT=0 environment variable) or are using the /build API endpoint. All users on versions older than 23.0 could be impacted. Image build API endpoint (/build) and ImageBuild function from github.com/docker/docker/client is also affected as it the uses classic builder by default. Patches are included in 24.0.9 and 25.0.2 releases.

Summary
Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby, is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in dockerd and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The overlay network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the u32 iptables extension provided by the xt_u32 kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
Two iptables rules serve to filter incoming VXLAN datagrams with a VNI that corresponds to an encrypted network and discards unencrypted datagrams. The rules are appended to the end of the INPUT filter chain, following any rules that have been previously set by the system administrator. Administrator-set rules take precedence over the rules Moby sets to discard unencrypted VXLAN datagrams, which can potentially admit unencrypted datagrams that should have been discarded.
The injection of arbitrary Ethernet frames can enable a Denial of Service attack. A sophisticated attacker may be able to establish a UDP or TCP connection by way of the container’s outbound gateway that would otherwise be blocked by a stateful firewall, or carry out other escalations beyond simple injection by smuggling packets into the overlay network.
Patches are available in Moby releases 23.0.3 and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. Close the VXLAN port (by default, UDP port 4789) to incoming traffic at the Internet boundary to prevent all VXLAN packet injection, and/or ensure that the `xt_u32` kernel module is available on all nodes of the Swarm cluster.

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up properly.

Summary
Moby is an open-source project created by Docker to enable and accelerate software containerization. A bug was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during `execve(2)`. Normally, when executable programs have specified permitted file capabilities, otherwise unprivileged users and processes can execute those programs and gain the specified file capabilities up to the bounding set. Due to this bug, containers which included executable programs with inheritable file capabilities allowed otherwise unprivileged users and processes to additionally gain these inheritable file capabilities up to the container's bounding set. Containers which use Linux users and groups to perform privilege separation inside the container are most directly impacted. This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container's bounding set. This bug has been fixed in Moby (Docker Engine) 20.10.14. Running containers should be stopped, deleted, and recreated for the inheritable capabilities to be reset. This fix changes Moby (Docker Engine) behavior such that containers are started with a more typical Linux environment. As a workaround, the entry point of a container can be modified to use a utility like `capsh(1)` to drop inheritable capabilities prior to the primary process starting.

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade limit access to the host to trusted users. Limit access to host volumes to trusted containers.

Summary
Moby is an open-source project created by Docker to enable software containerization. The classic builder cache system is prone to cache poisoning if the image is built FROM scratch. Also, changes to some instructions (most important being HEALTHCHECK and ONBUILD) would not cause a cache miss. An attacker with the knowledge of the Dockerfile someone is using could poison their cache by making them pull a specially crafted image that would be considered as a valid cache candidate for some build steps. 23.0+ users are only affected if they explicitly opted out of Buildkit (DOCKER_BUILDKIT=0 environment variable) or are using the /build API endpoint. All users on versions older than 23.0 could be impacted. Image build API endpoint (/build) and ImageBuild function from github.com/docker/docker/client is also affected as it the uses classic builder by default. Patches are included in 24.0.9 and 25.0.2 releases.

Summary
Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby, is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in dockerd and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The overlay network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the u32 iptables extension provided by the xt_u32 kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
Two iptables rules serve to filter incoming VXLAN datagrams with a VNI that corresponds to an encrypted network and discards unencrypted datagrams. The rules are appended to the end of the INPUT filter chain, following any rules that have been previously set by the system administrator. Administrator-set rules take precedence over the rules Moby sets to discard unencrypted VXLAN datagrams, which can potentially admit unencrypted datagrams that should have been discarded.
The injection of arbitrary Ethernet frames can enable a Denial of Service attack. A sophisticated attacker may be able to establish a UDP or TCP connection by way of the container’s outbound gateway that would otherwise be blocked by a stateful firewall, or carry out other escalations beyond simple injection by smuggling packets into the overlay network.
Patches are available in Moby releases 23.0.3 and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. Close the VXLAN port (by default, UDP port 4789) to incoming traffic at the Internet boundary to prevent all VXLAN packet injection, and/or ensure that the `xt_u32` kernel module is available on all nodes of the Swarm cluster.

"value": "Moby es un framework de contenedores de c\u00f3digo abierto desarrollado por Docker Inc. que se distribuye como Docker, Mirantis Container Runtime y varios otros proyectos/productos posteriores. El componente Moby daemon (`dockerd`), que se desarrolla como moby/moby, se conoce com\u00fanmente como *Docker*. El modo Swarm, que se compila y entrega de forma predeterminada en Dockerd y, por lo tanto, est\u00e1 presente en la mayor\u00eda de las principales versiones de Moby, es un orquestador de contenedores integrado y simple que se implementa mediante una combinaci\u00f3n de SwarmKit y c\u00f3digo de red de soporte. El controlador de red superpuesta es una caracter\u00edstica central del modo Swarm, que proporciona LAN virtuales aisladas que permiten la comunicaci\u00f3n entre contenedores y servicios en todo el cl\u00faster. Este controlador es una implementaci\u00f3n/usuario de VXLAN, que encapsula tramas de capa de enlace (Ethernet) en datagramas UDP que etiquetan la trama con un ID de red VXLAN (VNI) que identifica la red superpuesta de origen. Adem\u00e1s, el controlador de red superpuesta admite un modo cifrado opcional, desactivado de forma predeterminada, que resulta especialmente \u00fatil cuando los paquetes VXLAN atraviesan una red que no es de confianza entre nodos. Las redes superpuestas cifradas funcionan encapsulando los datagramas VXLAN mediante el uso del protocolo IPsec Encapsulating Security Payload en modo Transporte. Al implementar la encapsulaci\u00f3n IPSec, las redes superpuestas cifradas obtienen propiedades adicionales de autenticaci\u00f3n de origen mediante prueba criptogr\u00e1fica, integridad de datos mediante suma de verificaci\u00f3n y confidencialidad mediante cifrado. Al configurar un endpoint en una red superpuesta cifrada, Moby instala tres reglas de iptables (firewall del kernel de Linux) que aplican IPSec tanto entrante como saliente. Estas reglas se basan en la extensi\u00f3n u32 iptables proporcionada por el m\u00f3dulo del kernel xt_u32 para filtrar directamente el campo VNI de un paquete VXLAN, de modo que las garant\u00edas IPSec se puedan aplicar en redes superpuestas cifradas sin interferir con otras redes superpuestas u otros usuarios de VXLAN. Dos reglas de iptables sirven para filtrar datagramas VXLAN entrantes con un VNI que corresponde a una red cifrada y descarta los datagramas no cifrados. Las reglas se agregan al final de la cadena de filtros de ENTRADA, siguiendo las reglas que haya establecido previamente el administrador del sistema. Las reglas establecidas por el administrador tienen prioridad sobre las reglas que Moby establece para descartar datagramas VXLAN no cifrados, que potencialmente pueden admitir datagramas no cifrados que deber\u00edan haberse descartado. La inyecci\u00f3n de tramas Ethernet arbitrarias puede permitir un ataque de denegaci\u00f3n de servicio. Un atacante sofisticado puede establecer una conexi\u00f3n UDP o TCP a trav\u00e9s de la puerta de enlace de salida del contenedor que, de otro modo, ser\u00eda bloqueada por un firewall con estado, o llevar a cabo otras escaladas m\u00e1s all\u00e1 de la simple inyecci\u00f3n mediante el contrabando de paquetes en la red superpuesta. Los parches est\u00e1n disponibles en las versiones 23.0.3 y 20.10.24 de Moby. Como las versiones 20.10 de Mirantis Container Runtime tienen numeraci\u00f3n diferente, los usuarios de esa plataforma deben actualizar a la versi\u00f3n 20.10.16. Algunos workarounds est\u00e1n disponibles. Cierre el puerto VXLAN (de forma predeterminada, el puerto UDP 4789) al tr\u00e1fico entrante en el l\u00edmite de Internet para evitar toda inyecci\u00f3n de paquetes VXLAN y/o aseg\u00farese de que el m\u00f3dulo del kernel `xt_u32` est\u00e9 disponible en todos los nodos del cl\u00faster Swarm."

Summary
Moby) is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in `dockerd` and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The `overlay` network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with the VXLAN metadata, including a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the `u32` iptables extension provided by the `xt_u32` kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
The `overlay` driver dynamically and lazily defines the kernel configuration for the VXLAN network on each node as containers are attached and detached. Routes and encryption parameters are only defined for destination nodes that participate in the network. The iptables rules that prevent encrypted overlay networks from accepting unencrypted packets are not created until a peer is available with which to communicate.
Encrypted overlay networks silently accept cleartext VXLAN datagrams that are tagged with the VNI of an encrypted overlay network. As a result, it is possible to inject arbitrary Ethernet frames into the encrypted overlay network by encapsulating them in VXLAN datagrams. The implications of this can be quite dire, and GHSA-vwm3-crmr-xfxw should be referenced for a deeper exploration.
Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. In multi-node clusters, deploy a global ‘pause’ container for each encrypted overlay network, on every node. For a single-node cluster, do not use overlay networks of any sort. Bridge networks provide the same connectivity on a single node and have no multi-node features. The Swarm ingress feature is implemented using an overlay network, but can be disabled by publishing ports in `host` mode instead of `ingress` mode (allowing the use of an external load balancer), and removing the `ingress` network. If encrypted overlay networks are in exclusive use, block UDP port 4789 from traffic that has not been validated by IPSec.

"value": "Moby) es un framework de contenedores de c\u00f3digo abierto desarrollado por Docker Inc. que se distribuye como Docker, Mirantis Container Runtime y varios otros proyectos/productos posteriores. El componente Moby daemon (`dockerd`), que se desarrolla como moby/moby, se conoce com\u00fanmente como *Docker*. El modo Swarm, que se compila y entrega de forma predeterminada en \"dockerd\" y, por lo tanto, est\u00e1 presente en la mayor\u00eda de las principales versiones de Moby, es un orquestador de contenedores simple e integrado que se implementa mediante una combinaci\u00f3n de SwarmKit y soportando un c\u00f3digo de red. El controlador de red \"superpuesto\" es una caracter\u00edstica central del modo Swarm, que proporciona LAN virtuales aisladas que permiten la comunicaci\u00f3n entre contenedores y servicios en todo el cl\u00faster. Este controlador es una implementaci\u00f3n/usuario de VXLAN, que encapsula tramas de capa de enlace (Ethernet) en datagramas UDP que etiquetan la trama con los metadatos de VXLAN, incluido un ID de red VXLAN (VNI) que identifica la red superpuesta de origen. Adem\u00e1s, el controlador de red superpuesta admite un modo cifrado opcional, desactivado de forma predeterminada, que resulta especialmente \u00fatil cuando los paquetes VXLAN atraviesan una red que no es de confianza entre nodos. Las redes superpuestas cifradas funcionan encapsulando los datagramas VXLAN mediante el uso del protocolo IPsec Encapsulating Security Payload en modo Transporte. Al implementar la encapsulaci\u00f3n IPSec, las redes superpuestas cifradas obtienen propiedades adicionales de autenticaci\u00f3n de origen mediante prueba criptogr\u00e1fica, integridad de datos mediante suma de verificaci\u00f3n y confidencialidad mediante cifrado. Al configurar un endpoint en una red superpuesta cifrada, Moby instala tres reglas de iptables (firewall del kernel de Linux) que aplican IPSec tanto entrante como saliente. Estas reglas se basan en la extensi\u00f3n iptables `u32` proporcionada por el m\u00f3dulo del kernel `xt_u32` para filtrar directamente el campo VNI de un paquete VXLAN, de modo que las garant\u00edas IPSec se puedan aplicar en redes superpuestas cifradas sin interferir con otras redes superpuestas u otros usuarios de VXLAN. El controlador `overlay` define de forma din\u00e1mica y perezosa la configuraci\u00f3n del kernel para la red VXLAN en cada nodo a medida que los contenedores se conectan y desconectan. Las rutas y los par\u00e1metros de cifrado solo se definen para los nodos de destino que participan en la red. Las reglas de iptables que impiden que las redes superpuestas cifradas acepten paquetes no cifrados no se crean hasta que haya un interlocutor disponible con el que comunicarse. Las redes superpuestas cifradas aceptan silenciosamente datagramas VXLAN de texto sin cifrar etiquetados con el VNI de una red superpuesta cifrada. Como resultado, es posible inyectar tramas Ethernet arbitrarias en la red superpuesta cifrada encapsul\u00e1ndolas en datagramas VXLAN. Las implicaciones de esto pueden ser bastante nefastas, y se debe hacer referencia a GHSA-vwm3-crmr-xfxw para una exploraci\u00f3n m\u00e1s profunda. Los parches est\u00e1n disponibles en las versiones 23.0.3 y 20.10.24 de Moby. Como las versiones 20.10 de Mirantis Container Runtime tienen numeraci\u00f3n diferente, los usuarios de esa plataforma deben actualizar a la versi\u00f3n 20.10.16. Algunos workarounds est\u00e1n disponibles. En cl\u00fasteres de m\u00faltiples nodos, implemente un contenedor de \"pausa\" global para cada red superpuesta cifrada, en cada nodo. Para un cl\u00faster de un solo nodo, no utilice redes superpuestas de ning\u00fan tipo. Las redes puente brindan la misma conectividad en un solo nodo y no tienen funciones de m\u00faltiples nodos. La funci\u00f3n de ingreso de Swarm se implementa usando una red superpuesta, pero se puede deshabilitar publicando puertos en modo \"host\" en lugar del modo \"ingress\" (permitiendo el uso de un balanceador de carga externo) y eliminando la red de \"ingress\". Si las redes superpuestas cifradas son de uso exclusivo, bloquee el puerto UDP 4789 del tr\u00e1fico que no haya sido validado por IPSec."

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.

Summary
An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems. This allowed a client with any domain validated certificate signed by a system-trusted root CA (as opposed to one signed by the configured CA root certificate) to authenticate.

Summary
Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up properly.

Summary
The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.

Summary
Moby is an open-source project created by Docker to enable and accelerate software containerization. A bug was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during `execve(2)`. Normally, when executable programs have specified permitted file capabilities, otherwise unprivileged users and processes can execute those programs and gain the specified file capabilities up to the bounding set. Due to this bug, containers which included executable programs with inheritable file capabilities allowed otherwise unprivileged users and processes to additionally gain these inheritable file capabilities up to the container's bounding set. Containers which use Linux users and groups to perform privilege separation inside the container are most directly impacted. This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container's bounding set. This bug has been fixed in Moby (Docker Engine) 20.10.14. Running containers should be stopped, deleted, and recreated for the inheritable capabilities to be reset. This fix changes Moby (Docker Engine) behavior such that containers are started with a more typical Linux environment. As a workaround, the entry point of a container can be modified to use a utility like `capsh(1)` to drop inheritable capabilities prior to the primary process starting.

Fue encontrado un bug en Moby (Docker Engine) versiones anteriores a 20.10.14, en el que los contenedores eran iniciados incorrectamente con capacidades de proceso Linux heredables no vac\u00edas, creando un entorno Linux at\u00edpico y permitiendo que los programas con capacidades de archivo heredables elevaran esas capacidades al conjunto permitido durante \"execve(2)\". Normalmente, cuando los programas ejecutables presentan capacidades de archivo permitidas especificadas, los usuarios y procesos no privilegiados pueden ejecutar esos programas y conseguir las capacidades de archivo especificadas hasta el conjunto permitido. Debido a este bug, los contenedores que inclu\u00edan programas ejecutables con capacidades de archivo heredables permit\u00edan que usuarios y procesos no privilegiados consiguieran adicionalmente estas capacidades de archivo heredables hasta el conjunto de l\u00edmites del contenedor. Los contenedores que usan usuarios y grupos de Linux para llevar a cabo la separaci\u00f3n de privilegios dentro del contenedor son los m\u00e1s directamente afectados. Este bug no afectaba a la caja de arena de seguridad del contenedor, ya que el conjunto heredable nunca conten\u00eda m\u00e1s capacidades que las incluidas en el conjunto delimitador del contenedor. Este bug ha sido corregido en Moby (Docker Engine) versi\u00f3n 20.10.14. Los contenedores en ejecuci\u00f3n deben detenerse, eliminarse y volver a crearse para que sean restablecidas las capacidades heredables. Esta correcci\u00f3n cambia el comportamiento de Moby (Docker Engine) para que los contenedores se inicien con un entorno Linux m\u00e1s t\u00edpico. Como medida de mitigaci\u00f3n, el punto de entrada de un contenedor puede modificarse para usar una utilidad como \"capsh(1)\" para eliminar las capacidades heredables antes de que sea iniciado el proceso primario"

Summary
Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby is commonly referred to as *Docker*.
Swarm Mode, which is compiled in and delivered by default in `dockerd` and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code.
The `overlay` network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with the VXLAN metadata, including a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes.
Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption.
When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the `u32` iptables extension provided by the `xt_u32` kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN.
An iptables rule designates outgoing VXLAN datagrams with a VNI that corresponds to an encrypted overlay network for IPsec encapsulation.
Encrypted overlay networks on affected platforms silently transmit unencrypted data. As a result, `overlay` networks may appear to be functional, passing traffic as expected, but without any of the expected confidentiality or data integrity guarantees.
It is possible for an attacker sitting in a trusted position on the network to read all of the application traffic that is moving across the overlay network, resulting in unexpected secrets or user data disclosure. Thus, because many database protocols, internal APIs, etc. are not protected by a second layer of encryption, a user may use Swarm encrypted overlay networks to provide confidentiality, which due to this vulnerability this is no longer guaranteed.
Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.
Some workarounds are available. Close the VXLAN port (by default, UDP port 4789) to outgoing traffic at the Internet boundary in order to prevent unintentionally leaking unencrypted traffic over the Internet, and/or ensure that the `xt_u32` kernel module is available on all nodes of the Swarm cluster.

"value": "Moby es un framework de contenedores de c\u00f3digo abierto desarrollado por Docker Inc. que se distribuye como Docker, Mirantis Container Runtime y varios otros proyectos/productos posteriores. El componente Moby daemon (`dockerd`), que se desarrolla como moby/moby, se conoce com\u00fanmente como *Docker*. El modo Swarm, que se compila y entrega de forma predeterminada en \"dockerd\" y, por lo tanto, est\u00e1 presente en la mayor\u00eda de las principales versiones de Moby, es un orquestador de contenedores simple e integrado que se implementa mediante una combinaci\u00f3n de SwarmKit y c\u00f3digo de red de soporte. El controlador de red \"superpuesto\" es una caracter\u00edstica central del modo Swarm, que proporciona LAN virtuales aisladas que permiten la comunicaci\u00f3n entre contenedores y servicios en todo el cl\u00faster. Este controlador es una implementaci\u00f3n/usuario de VXLAN, que encapsula tramas de capa de enlace (Ethernet) en datagramas UDP que etiquetan la trama con los metadatos de VXLAN, incluido un ID de red VXLAN (VNI) que identifica la red superpuesta de origen. Adem\u00e1s, el controlador de red superpuesta admite un modo cifrado opcional, desactivado de forma predeterminada, que resulta especialmente \u00fatil cuando los paquetes VXLAN atraviesan una red que no es de confianza entre nodos. Las redes superpuestas cifradas funcionan encapsulando los datagramas VXLAN mediante el uso del protocolo IPsec Encapsulating Security Payload en modo Transporte. Al implementar la encapsulaci\u00f3n IPSec, las redes superpuestas cifradas obtienen propiedades adicionales de autenticaci\u00f3n de origen mediante prueba criptogr\u00e1fica, integridad de datos mediante suma de verificaci\u00f3n y confidencialidad mediante cifrado.Al configurar un endpoint en una red superpuesta cifrada, Moby instala tres reglas de iptables (firewall del kernel de Linux) que aplican IPSec tanto entrante como saliente. Estas reglas se basan en la extensi\u00f3n iptables `u32` proporcionada por el m\u00f3dulo del kernel `xt_u32` para filtrar directamente el campo VNI de un paquete VXLAN, de modo que las garant\u00edas IPSec se puedan aplicar en redes superpuestas cifradas sin interferir con otras redes superpuestas u otros usuarios de VXLAN. Una regla de iptables designa datagramas VXLAN salientes con un VNI que corresponde a una red superpuesta cifrada para encapsulaci\u00f3n IPsec. Las redes superpuestas cifradas en las plataformas afectadas transmiten silenciosamente datos no cifrados. Como resultado, las redes \"superpuestas\" pueden parecer funcionales, pasando el tr\u00e1fico como se esperaba, pero sin ninguna de las garant\u00edas esperadas de confidencialidad o integridad de los datos. Es posible que un atacante ubicado en una posici\u00f3n confiable en la red lea todo el tr\u00e1fico de aplicaciones que se mueve a trav\u00e9s de la red superpuesta, lo que resulta en secretos inesperados o divulgaci\u00f3n de datos del usuario. Por lo tanto, debido a que muchos protocolos de bases de datos, API internas, etc. no est\u00e1n protegidos por una segunda capa de cifrado, un usuario puede utilizar redes superpuestas cifradas Swarm para proporcionar confidencialidad, que debido a esta vulnerabilidad ya no est\u00e1 garantizada. Los parches est\u00e1n disponibles en las versiones 23.0.3 y 20.10.24 de Moby. Como las versiones 20.10 de Mirantis Container Runtime tienen numeraci\u00f3n diferente, los usuarios de esa plataforma deben actualizar a la versi\u00f3n 20.10.16. Algunos workarounds est\u00e1n disponibles. Cierre el puerto VXLAN (de forma predeterminada, el puerto UDP 4789) al tr\u00e1fico saliente en el l\u00edmite de Internet para evitar fugas involuntarias de tr\u00e1fico no cifrado a trav\u00e9s de Internet y/o aseg\u00farese de que el m\u00f3dulo del kernel `xt_u32` est\u00e9 disponible en todos los nodos del grupo Swarm."
