Synopsis
=======
A buffer overflow in TigerVNC could result in execution of arbitrary
code or Denial of Service.

Background
=========
TigerVNC is a high-performance VNC server/client.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/tigervnc            < 1.3.1                    >= 1.3.1

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"
