TigerVNC: User-assisted execution of arbitrary code — GLSA 201411-03

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

Affected Packages

net-misc/tigervnc on all architectures
Affected versions < 1.3.1
Unaffected versions >= 1.3.1

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"
