Description

Background

Real VNC is a remote desktop viewer display system.

Description

An unspecified vulnerability has been discovered int the CMsgReader::readRect() function in the VNC Viewer component, related to the encoding type of RFB protocol data.

Impact

A remote attacker could entice a user to connect to a malicious VNC server, or leverage Man-in-the-Middle attacks, to cause the execution of arbitrary code with the privileges of the user running the VNC viewer.

Workaround

There is no known workaround at this time.

Resolution

All Real VNC users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-misc/vnc-4.1.3"
