tag_summary = "The 'httpdx' program is prone to multiple remote buffer-overflow
   vulnerabilities because the application fails to perform adequate
   boundary-checks on user-supplied data.

   An attacker can exploit these issues to execute arbitrary code
   within the context of the affected application. Failed exploit
   attempts will result in a denial-of-service condition.

   These issues affect httpdx 0.5b; other versions may also be
   affected.";
