             * Synopsis: Security Vulnerabilities in QT Library May Allow a Remote
             Unprivileged User to Execute Arbitrary Code
             * Category: Security
             * Product: Sun Java Desktop System(JDS)
             * BugIDs: 5090119
             * Avoidance: Patch
             * State: Resolved

1. Impact

       Due to multiple vulnerabilities in libqt, a remote unprivileged user may
       be able to execute arbitrary code with the privileges of a local user when
       that local user has loaded a Bitmap (.bmp) format image file, XPixMap
       (.xpm) format image file or a Graphics Interchange Format (.gif) format
       image file supplied by an untrusted remote user.

       Note: QT is a multiplatform C++ GUI application framework. It is used in
       many popular Open Source projects such as KDE.

       This issue is described in the following documents:

2. Contributing Factors

       This issue can occur in the following releases:

       Linux
             * Sun Java Desktop System (JDS) 2003 without the updated RPMs
             (patch-9278)
             * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
             (patch-9278)
       Note: JDS for Solaris is not impacted by this issue.

       This issue only occurs with QT Library versions qt3-3.1.1-117 or earlier.

       To determine the release of JDS for Linux installed on a system, the
       following command can be run:

       % cat /etc/sun-release
       Sun Java Desktop System, Release 2 -build 10b (GA)
       Assembled 30 March 2004

       To determine the version of QT Library, the following command can be run:

       % rpm -qf /usr/lib/libqt-mt.so.3
       qt3-3.1.1-117
