Update Summary

USN-8718-1 addresses an SSSD vulnerability where specially crafted input could crash the daemon. On Ubuntu Server 24.04 LTS, update `sssd-common` to 2.9.4-1.1ubuntu6.8 and restart `sssd` after updating.

Update Details

Security

  • SSSD did not properly validate authentication token lengths when processing PAM responder requests, which could let a local attacker cause a denial of service by crashing sssd.

Hints

  • After a standard system update, restart sssd to apply the changes.
  • For Ubuntu Server 24.04 LTS (noble), the fixed package version is sssd-common 2.9.4-1.1ubuntu6.8.
