A flaw was found in GSS-NTLMSSP, a mechglue plugin for the GSSAPI library that implements NTLM authentication. 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 issue will likely trigger an assertion failure in free,
causing a denial of service.
