NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd package and not the sssd package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure.
