An integer overflow flaw in the Qt pixmap handling could possibly lead to a Denial of Service or the remote execution of arbitrary code.
|Package||x11-libs/qt on all architectures|
|Affected versions||< 4.1.4-r2|
|Unaffected versions||>= 4.1.4-r2, revision >= 3.3.6-r4, revision >= 3.3.8, revision >= 3.3.8b|
Qt is a cross-platform GUI toolkit, which is used e.g. by KDE.
An integer overflow flaw has been found in the pixmap handling of Qt.
By enticing a user to open a specially crafted pixmap image in an application using Qt, e.g. Konqueror, a remote attacker could be able to cause an application crash or the execution of arbitrary code with the rights of the user running the application.
There is no known workaround at this time.
All Qt 3.x users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.6-r4"
All Qt 4.x users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/qt-4.1.4-r2"
