Helix Servers View Source Plug-in RTSP Parser Overflow

critical Nessus Plugin ID 11642

Language:

Synopsis

The remote media streaming server is susceptible to buffer overflow attacks.

Description

The remote host is running RealServer or Helix Universal Server, media streaming servers.

According to its banner, the version of the server installed on the remote host may be affected by a buffer overflow vulnerability when handling URLs with many '/' characters and another when handling unspecified RTSP methods. Using a specially crafted request, an attacker may be able to leverage either of these issues to execute arbitrary code subject to the privileges of the user under which the server operates, generally root or Administrator.

Solution

Install the Helix Universal Server 9.01 Security Update or later.
