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)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
