Name of the Vulnerable Software and Affected Versions
GSS-NTLMSSP versions prior to 1.2.0
Description
The issue is related to an incorrect free when decoding target information, which can trigger a denial of service. This occurs because the error condition incorrectly assumes the
cb and sh buffers contain a copy of the data that needs to be freed. The vulnerability can be triggered via the main gss accept sec context entry point, likely causing an assertion failure in free.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 until the update is applied.Exploitability
