NVD Description

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

GNU SASL before 2.2.4 lacks sanitization of a short challenge in _gsasl_ntlm_client_step in the NTLM client, which could result in memory disclosure via a crafted server.
