CVE-2023-25566

GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements
NTLM authentication. Prior to version 1.2.0, a memory leak can be triggered
when parsing usernames which can trigger a denial-of-service. The domain
portion of a username may be overridden causing an allocated memory area
the size of the domain name to be leaked. An attacker can leak memory via
the main gss_accept_sec_context entry point, potentially causing a
denial-of-service. This issue is fixed in version 1.2.0.
