Synopsis

The remote web server hosts a VNC application that is affected by a heap-based buffer overflow vulnerability.

Description

According to its self-identified version number, the TigerVNC install hosted on the remote web server is affected by a heap-based buffer overflow vulnerability.

A flaw exists when performing bounds check during ZRLE decoding. This could allow a remote attacker with a malicious server and a specially crafted request to execute arbitrary code.

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

Solution

Upgrade to version 1.3.1 or later.
