Synopsis
========

VMware may load shared libraries from an untrusted, world-writable
directory, resulting in the execution of arbitrary code.

Background
==========

VMware Workstation is a powerful virtual machine for developers and
system administrators.

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

    -------------------------------------------------------------------
     Package             /     Vulnerable     /             Unaffected
    -------------------------------------------------------------------
  1  vmware-workstation      < 4.5.2.8848-r5          >= 4.5.2.8848-r5

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

Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered
that VMware Workstation searches for gdk-pixbuf loadable modules in an
untrusted, world-writable directory.

Impact
======

A local attacker could create a malicious shared object that would be
loaded by VMware, resulting in the execution of arbitrary code with the
privileges of the user running VMware.

Workaround
==========

The system administrator may create the file /tmp/rrdharan to prevent
malicious users from creating a directory at that location:

    # touch /tmp/rrdharan

Resolution
==========

All VMware Workstation users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/vmware-workstation-4.5.2.8848-r5"

Availability
============

This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:

Concerns?
=========

Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@gentoo.org or alternatively, you may file a bug at
