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 < 3.3.4-r2 >= 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 ">=x11-libs/qt-3.3.4-r2"

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

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