Helix RealServer < 11.1.0.801 Remote Overflow

High

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote host is running the Helix RealServer streaming media server. All versions of Helix 10.0.x and 11.0.x are vulnerable to multiple remote buffer overflows. Apparently, the application does not properly sanitize malformed HTTP requests. An attacker exploiting this flaw would only need to be able to send HTTP requests to the Helix server. Successful exploitation would result in the attacker executing arbitrary code.

Solution

Upgrade to version 11.1.0.801 or higher.
