|Gentoo Linux Security Advisory
Title: Qt: Buffer overflow in the included zlib library (GLSA 200509-18)
Date: September 26, 2005
Qt is vulnerable to a buffer overflow which could potentially lead to the execution of arbitrary code.
Qt is a cross-platform GUI toolkit used by KDE.
Vulnerable: < 3.3.4-r8
Unaffected: >= 3.3.4-r8
Architectures: All supported architectures
Qt links to a bundled vulnerable version of zlib when emerged with the zlib USE-flag disabled. This may lead to a buffer overflow.
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.
Emerge Qt with the zlib USE-flag enabled.
All Qt users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8"
