tag_summary = "CoreHTTP is prone to a buffer-overflow vulnerability because it fails
to adequately bounds-check user-supplied data.

Attackers can exploit this issue to execute arbitrary code within the
context of the affected application. Failed exploit attempts will
result in a denial of service.

This issue affects CoreHTTP 0.5.3.1. ; other versions may also
be affected.";
