Date: September 26, 2005
Bugs: #100683
ID: 200509-18

Synopsis
========
Qt is vulnerable to a buffer overflow which could potentially lead to
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-r8 >= 3.3.4-r8
Description
===========
Qt links to a bundled vulnerable version of zlib when emerged with the
zlib USE-flag disabled. This may lead to a buffer overflow.
Impact
======
By creating a specially crafted compressed data stream, attackers can
overwrite data structures for applications that use Qt, resulting in a
Denial of Service or potentially arbitrary code execution.
Workaround
==========
Emerge Qt with the zlib USE-flag enabled.
Resolution
==========
All Qt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8"
Availability
============
This GLSA and any updates to it are available for viewing at
