Synopsis
========

A vulnerability in LibXcursor might allow remote attackers to execute
arbitrary code.

Background
==========

X.Org X11 libXcursor runtime library. 

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  x11-libs/libXcursor          < 1.1.15                  >= 1.1.15 

Description
===========

It was discovered that libXcursor is prone to several heap overflows
when parsing malicious files.

Impact
======

A remote attacker, by enticing a user to process a specially crafted
cursor file, could possibly execute arbitrary code with the privileges
of the process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LibXcursor users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=x11-libs/libXcursor-1.1.15"
