Astra Linux – Vulnerability in Containerd

Containerd is a container runtime. A bug was discovered in containerd versions prior to 1.4.8 and 1.5.4, where pulling and extracting a specially crafted container image could result in changes to Unix file permissions for existing files in the host’s filesystem. Changes to file permissions could...

kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...
