Gentoo Linux Security Advisory

Title: TigerVNC: User-assisted execution of arbitrary code (GLSA 201411-03)
Severity: normal
Exploitable: remote
Date: November 05, 2014
Bug(s): #505170
ID: 201411-03

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: net-misc/tigervnc
Vulnerable: < 1.3.1
Unaffected: >= 1.3.1
Architectures: All supported architectures


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