========================================================================== Ubuntu Security Notice USN-4889-1 March 25, 2021
linux, linux-lts-xenial vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
Details:
Adam Nichols discovered that heap overflows existed in the iSCSI subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-27365)
Adam Nichols discovered that the iSCSI subsystem in the Linux kernel did not properly restrict access to iSCSI transport handles. A local attacker could use this to cause a denial of service or expose sensitive information (kernel pointer addresses). (CVE-2021-27363)
Adam Nichols discovered that an out-of-bounds read existed in the iSCSI subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2021-27364)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-3.13.0-185-generic 3.13.0-185.236 linux-image-3.13.0-185-generic-lpae 3.13.0-185.236 linux-image-3.13.0-185-lowlatency 3.13.0-185.236 linux-image-4.4.0-206-generic 4.4.0-206.238~14.04.1 linux-image-4.4.0-206-generic-lpae 4.4.0-206.238~14.04.1 linux-image-4.4.0-206-lowlatency 4.4.0-206.238~14.04.1 linux-image-generic 3.13.0.185.194 linux-image-generic-lpae 3.13.0.185.194 linux-image-generic-lpae-lts-xenial 4.4.0.206.179 linux-image-generic-lts-xenial 4.4.0.206.179 linux-image-generic-pae 3.13.0.185.194 linux-image-lowlatency 3.13.0.185.194 linux-image-lowlatency-lts-xenial 4.4.0.206.179 linux-image-lowlatency-pae 3.13.0.185.194 linux-image-server 3.13.0.185.194 linux-image-virtual 3.13.0.185.194 linux-image-virtual-lts-xenial 4.4.0.206.179
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.
