Description

Background

TigerVNC is a high-performance VNC server/client.

Description

Two boundary errors in TigerVNC could lead to a heap-based buffer overflow.

Impact

A remote attacker could entice a user to connect to a malicious VNC server using TigerVNC, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All TigerVNC users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-misc/tigervnc-1.3.1"
