Severity: Normal Title: Qt: Buffer overflow in the included zlib library 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 the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200509-18.xml
