Vulnerability from variot
When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds. Linux Kernel Exists in an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ========================================================================== Ubuntu Security Notice USN-5580-1 August 24, 2022
linux-aws vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems
Details:
It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655)
It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. A remote attacker could use this to expose sensitive information (kernel memory). (CVE-2022-20368)
Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-36946)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 ESM: linux-image-4.4.0-1150-aws 4.4.0-1150.165 linux-image-aws 4.4.0.1150.154
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

"data": "When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds. Linux Kernel Exists in an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ==========================================================================\nUbuntu Security Notice USN-5580-1\nAugust 24, 2022\n\nlinux-aws vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 16.04 ESM\n\nSummary:\n\nSeveral security issues were fixed in the Linux kernel. \n\nSoftware Description:\n- linux-aws: Linux kernel for Amazon Web Services (AWS) systems\n\nDetails:\n\nIt was discovered that the framebuffer driver on the Linux kernel did \nnot verify size limits when changing font or screen size, leading to an \nout-of-bounds write. A local attacker could use this to cause a denial \nof service (system crash) or possibly execute arbitrary code. \n(CVE-2021-33655)\n\nIt was discovered that the virtual terminal driver in the Linux kernel \ndid not properly handle VGA console font changes, leading to an \nout-of-bounds write. A local attacker could use this to cause a denial \nof service (system crash) or possibly execute arbitrary code. A remote attacker could \nuse this to expose sensitive information (kernel memory). (CVE-2022-20368)\n\nDomingo Dirutigliano and Nicola Guerrera discovered that the netfilter\nsubsystem in the Linux kernel did not properly handle rules that \ntruncated packets below the packet header size. When such rules are in \nplace, a remote attacker could possibly use this to cause a denial of \nservice (system crash). (CVE-2022-36946)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 16.04 ESM:\n linux-image-4.4.0-1150-aws 4.4.0-1150.165\n linux-image-aws 4.4.0.1150.154\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. Description:\n\nRed Hat Advanced Cluster Management for Kubernetes 2.6.6 images\n\nRed Hat Advanced Cluster Management for Kubernetes provides the\ncapabilities to address common challenges that administrators and site\nreliability engineers face as they work across a range of public and\nprivate cloud environments. Clusters and applications are all visible and\nmanaged from a single console\u2014with security policy built in. \n\nThis advisory contains the container images for Red Hat Advanced Cluster\nManagement for Kubernetes, which fix several bugs. See the following\nRelease Notes documentation, which will be updated shortly for this\nrelease, for additional details about this release:\n\nhttps://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.6/html/release_notes/\n\nSecurity Fix(es):\n* CVE-2023-28856 redis: Insufficient validation of HINCRBYFLOAT command\n* CVE-2023-32314 vm2: Sandbox Escape\n* CVE-2023-32313 vm2: Inspect Manipulation\n\n3.
