A flaw was found in SSSD. The sss nss protocol parse addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
