NVD Description

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

A flaw was found in SSSD. A local attacker can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process and result in a denial of service (DoS).
