CVE-2023-25565
Date: February 14, 2023
GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the "cb" and "sh" buffers contain a copy of the data that needs to be freed. However, that is not the case. This vulnerability can be triggered via the main "gss_accept_sec_context" entry point. This will likely trigger an assertion failure in "free", causing a denial-of-service. This issue is fixed in version 1.2.0.
