Ubuntu Security Notice USN-6645-1
Ubuntu Security Notice 6645-1 - It was discovered that the netfilter connection tracker for netlink in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service.
==========================================================================Ubuntu Security Notice USN-6645-1February 20, 2024linux vulnerability==========================================================================A security issue affects these releases of Ubuntu and its derivatives:- Ubuntu 14.04 LTS (Available with Ubuntu Pro)Summary:The system could be made to stop responding under certain conditions.Software Description:- linux: Linux kernelDetails:It was discovered that the netfilter connection tracker for netlink in theLinux kernel did not properly perform reference counting in some errorconditions. A local attacker could possibly use this to cause a denial ofservice (memory exhaustion).Update instructions:The problem can be corrected by updating your system to the followingpackage versions:Ubuntu 14.04 LTS (Available with Ubuntu Pro): linux-image-3.13.0-196-generic 3.13.0-196.247 linux-image-3.13.0-196-lowlatency 3.13.0-196.247 linux-image-generic 3.13.0.196.206 linux-image-generic-lts-trusty 3.13.0.196.206 linux-image-lowlatency 3.13.0.196.206 linux-image-server 3.13.0.196.206 linux-image-virtual 3.13.0.196.206After a standard system update you need to reboot your computer to makeall the necessary changes.ATTENTION: Due to an unavoidable ABI change the kernel updates havebeen given a new version number, which requires you to recompile andreinstall 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 performthis as well.References: https://ubuntu.com/security/notices/USN-6645-1 CVE-2023-7192Related news
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.
