Ubuntu Security Notice USN-6866-3

linux-azure vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 14.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux-azure: Linux kernel for Microsoft Azure Cloud systems<\/p>\n
Details:<\/p>\n
It was discovered that the ext4 file system implementation in the Linux
kernel did not properly validate data state on write operations. An
attacker could use this to construct a malicious ext4 file system image
that, when mounted, could cause a denial of service (system crash).
(CVE-2021-33631)<\/p>\n
It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6270)<\/p>\n
Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)<\/p>\n
Gui-Dong Han discovered that the software RAID driver in the Linux kernel
contained a race condition, leading to an integer overflow vulnerability. A
privileged attacker could possibly use this to cause a denial of service
(system crash). (CVE-2024-23307)<\/p>\n
Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in
the Linux kernel contained a race condition, leading to an integer overflow
vulnerability. An attacker could possibly use this to cause a denial of
service (system crash). (CVE-2024-24861)<\/p>\n
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– Block layer subsystem;
– Hardware random number generator core;
– GPU drivers;
– AFS file system;
– Memory management;
– Netfilter;
(CVE-2024-26642, CVE-2024-26922, CVE-2024-26720, CVE-2024-26736,
CVE-2024-26898, CVE-2021-47063, CVE-2023-52615)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 14.04 LTS
linux-image-4.15.0-1178-azure 4.15.0-1178.193~14.04.1
Available with Ubuntu Pro
linux-image-azure 4.15.0.1178.193~14.04.1
Available with Ubuntu Pro<\/p>\n
After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
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.<\/p>\n
