Description

pam security update

PAM (Pluggable Authentication Modules) is a system of libraries that handle the authentication tasks of applications (services) on the system.

Security Fix(es):

A vulnerability was found in Linux PAM. An unprivileged user that is not yet in a corresponding mount namespace with ~/tmp mounted as a polyinstantiated dir can place a FIFO there, and a subsequent attempt to login as this user with pam_namespace configured will cause the openat() in protect_dir() to block the attempt, causing a local denial of service.(CVE-2024-22365)

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full
