TITLE

Linux Kernel Vulnerable to classic buffer overflow

DESCRIPTION

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Linux Kernel Contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. The following packages have been upgraded to a later upstream version: redhat-release-virtualization-host (4.3.5), redhat-virtualization-host (4.3.5). 7.3) - noarch, x86_64 3. (CVE-2019-14835) * kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * fs deadlock when a memory allocation waits on page writeback in NOFS context (BZ#1729105) * fragmented packets timing out (BZ#1729410) * kernel build: speed up debuginfo extraction (BZ#1731461) * use "make -jN" for modules_install (BZ#1735080) * shmem: consider shm_mnt as a long-term mount (BZ#1737375) * Backport TCP follow-up for small buffers (BZ#1739126) 4. ========================================================================== Kernel Live Patch Security Notice 0058-1 October 22, 2019 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu: | Series | Base kernel | Arch | flavors | |------------------+--------------+----------+------------------| | Ubuntu 18.04 LTS | 4.15.0 | amd64 | aws | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | generic | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | lowlatency | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | oem | | Ubuntu 18.04 LTS | 5.0.0 | amd64 | azure | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | aws | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | azure | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | generic | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | lowlatency | Summary: Several security issues were fixed in the kernel.

Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.199/*: Upgraded. These updates fix various bugs and security issues. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.

For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.199-smp | bash For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.199 | bash Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.199-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.199 as the version. If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting. If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader. If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition. +-----+ Slackware Linux Security Team http://slackware.com/gpg-key security@slackware.com +------------------------------------------------------------------------+ | To leave the slackware-security mailing list: | +------------------------------------------------------------------------+ | Send an email to majordomo@slackware.com with this text in the body of | | the email message: | | | | unsubscribe slackware-security | | | | You will get a confirmation message back containing instructions to | | complete the process.

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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2019:2829-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:2829 Issue date: 2019-09-20 CVE Names: CVE-2019-14835 ==================================================================== 1.
