Synopsis
=======

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

Background
=========

Qt is a cross-platform GUI toolkit used by KDE.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-libs/qt lt; 3.3.4-r2 gt;= 3.3.4-r2

Description
==========

Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered that Qt searches for shared libraries in an untrusted, world-writable directory.

Impact
=====

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

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All Qt users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=x11-libs/qt-3.3.4-r2"

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

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

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 http://bugs.gentoo.org.
