Summary
pam security update
Details

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)

Severity
5.5 (Medium)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
