A flaw was found in SSSD. A local attacker with access to the Name Service Switch (NSS) responder UNIX socket can trigger an integer underflow by sending a specially crafted request with an undersized packet header. This issue causes an out-of-bounds memory read during packet parsing, crashing the responder process and resulting in a Denial of Service (DoS).
