Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
An integer overflow flaw in the Qt pixmap handling could possibly lead
to a Denial of Service or the remote execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Qt is a cross-platform GUI toolkit, which is used e.g. by KDE.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
An integer overflow flaw has been found in the pixmap handling of Qt.
Impact
=3D=3D=3D=3D=3D=3D
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.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All Qt 3.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dx11-libs/qt-3.3.6-r4"
All Qt 4.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dx11-libs/qt-4.1.4-r2"
