Format string vulnerabilities in Qt 3 may lead to the remote execution of arbitrary code in some Qt applications.
|Package||x11-libs/qt on all architectures|
|Affected versions||< 3.3.8-r3|
|Unaffected versions||>= 3.3.8-r3|
Qt is a cross-platform GUI framework, which is used e.g. by KDE.
Tim Brown of Portcullis Computer Security Ltd and Dirk Mueller of KDE reported multiple format string errors in qWarning() calls in files qtextedit.cpp, qdatatable.cpp, qsqldatabase.cpp, qsqlindex.cpp, qsqlrecord.cpp, qglobal.cpp, and qsvgdevice.cpp.
An attacker could trigger one of the vulnerabilities by causing a Qt application to parse specially crafted text, which may lead to the execution of arbitrary code.
There is no known workaround at this time.
All Qt 3 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose "=x11-libs/qt-3*"
