The remote mail server is affected by a buffer overflow vulnerability.


The remote host is running a version of the Sendmail mail server earlier than 8.13.2. Such versions are reportedly affected by a remote buffer overflow vulnerability. An attacker could leverage this flaw to execute arbitrary code with the privileges of the affected application.
