NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd-krb5-common package and not the sssd-krb5-common package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
