NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd-ldap package and not the sssd-ldap package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in sssd. A local attacker can cause a Denial of Service (DoS) by sending a crafted Pluggable Authentication Module (PAM) request containing a zero-length authentication token to the responder socket. Due to missing input validation, the service attempts to read beyond buffer boundaries when processing the token, causing the PAM responder to crash.
