Vulnerability from csaf_redhat - Published: 2018-11-05 14:57 - Updated: 2024-11-25 12:11Summary
Red Hat Security Advisory: Red Hat Virtualization security and bug fix update
Notes
Topic
An update for imgbased, redhat-release-virtualization-host, and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.
Security Fix(es):
* spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial of service (CVE-2018-10873)
* glusterfs: Multiple flaws (CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, CVE-2018-10913)
* samba: Insufficient input validation in libsmbclient (CVE-2018-10858)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, and CVE-2018-10913. The CVE-2018-10873 issue was discovered by Frediano Ziglio (Red Hat).
Bug Fix(es):
* When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous layers, so new logical volumes are removed, and the boot entry points to a logical volume that was removed.
If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection fails. (BZ#1632058)
* During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation, causing the upgrade process to fail. Now the process uses "lvremove --force" when trying to remove logical volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes successfully. (BZ#1632585)

Vulnerability from csaf_redhat - Published: 2018-09-04 06:25 - Updated: 2025-11-21 18:05Summary
Red Hat Security Advisory: Red Hat Gluster Storage security, bug fix, and enhancement update
Notes
Topic
Updated glusterfs packages that fix multiple security issues, several bugs, and adds various enhancements are now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.
Security Fix(es):
* glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)
* glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)
* glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)
* glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)
* glusterfs: File status information leak and denial of service (CVE-2018-10927)
* glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)
* glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)
* glusterfs: Files can be renamed outside volume (CVE-2018-10930)
* glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)
* glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c (CVE-2018-10914)
* glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c (CVE-2018-10913)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting these issues.

Vulnerability from csaf_redhat - Published: 2018-11-05 14:57 - Updated: 2025-11-21 18:06Summary
Red Hat Security Advisory: Red Hat Virtualization security and bug fix update
Notes
Topic
An update for imgbased, redhat-release-virtualization-host, and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.
Security Fix(es):
* spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial of service (CVE-2018-10873)
* glusterfs: Multiple flaws (CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, CVE-2018-10913)
* samba: Insufficient input validation in libsmbclient (CVE-2018-10858)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661, and CVE-2018-10913. The CVE-2018-10873 issue was discovered by Frediano Ziglio (Red Hat).
Bug Fix(es):
* When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous layers, so new logical volumes are removed, and the boot entry points to a logical volume that was removed.
If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection fails. (BZ#1632058)
* During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation, causing the upgrade process to fail. Now the process uses "lvremove --force" when trying to remove logical volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes successfully. (BZ#1632585)

Red Hat Security Advisory: Red Hat Gluster Storage security, bug fix, and enhancement update
Notes
Topic
Updated glusterfs packages that fix multiple security issues and bugs, and add various enhancements are now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.
Security Fix(es):
* glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)
* glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)
* glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)
* glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)
* glusterfs: File status information leak and denial of service (CVE-2018-10927)
* glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)
* glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)
* glusterfs: Files can be renamed outside volume (CVE-2018-10930)
* glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)
* glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c (CVE-2018-10914)
* glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c (CVE-2018-10913)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat Security Advisory: Red Hat Gluster Storage security, bug fix, and enhancement update
Notes
Topic
Updated glusterfs packages that fix multiple security issues and bugs, and add various enhancements are now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnections into one large, parallel network file system.
Security Fix(es):
* glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code (CVE-2018-10904)
* glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code (CVE-2018-10907)
* glusterfs: I/O to arbitrary devices on storage server (CVE-2018-10923)
* glusterfs: Device files can be created in arbitrary locations (CVE-2018-10926)
* glusterfs: File status information leak and denial of service (CVE-2018-10927)
* glusterfs: Improper resolution of symlinks allows for privilege escalation (CVE-2018-10928)
* glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code (CVE-2018-10929)
* glusterfs: Files can be renamed outside volume (CVE-2018-10930)
* glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)
* glusterfs: remote denial of service of gluster volumes via posix_get_file_contents function in posix-helpers.c (CVE-2018-10914)
* glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c (CVE-2018-10913)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting these issues.
