"According to its banner, the version of Apache Traffic Server
running on the remote host is 3.0.x prior to 3.0.4 or 3.1.x prior to
3.1.3. It is, therefore, affected by a heap-based buffer overflow
vulnerability when handling malicious HTTP host headers. A remote,
unauthenticated attacker can exploit this to execute arbitrary code on
the remote host subject to the privileges of the user running the
affected application.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
