NVD Description

Note: Versions mentioned in the description apply only to the upstream sssd-ad package and not the sssd-ad package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose cached directory data and heap layout information from the sssd_nss process.
