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:
