CVE-2023-25566

Name of the Vulnerable Software and Affected Versions GSS-NTLMSSP versions prior to 1.2.0

Description GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. A memory leak can be triggered when parsing usernames, potentially causing 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.

Recommendations For versions prior to 1.2.0, update to version 1.2.0 to resolve the issue. As a temporary workaround, consider restricting the use of the gss accept sec context entry point to minimize the risk of exploitation.
