CVE-2024-22365  (opens in a new tab)

How to fix?

Upgrade Debian:14 pam to version 1.5.3-4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pam package and not the pam package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

linux-pam (aka Linux PAM) before 1.6.0 allows attackers to cause a denial of service (blocked login process) via mkfifo because the openat call (for protect_dir) lacks O_DIRECTORY.
