Description

Certain versions of Sendmail in the 8.12.x series do not properly initialize the DNS Map structure. As a result, a remote attacker can send an invalid DNS reply to cause Sendmail to free() uninitialized data, crashing the process. It is unknown if remote execution of arbitrary code is possible.
