(RHSA-2004:414) qt security update

Qt is a software toolkit that simplifies the task of writing and
maintaining GUI (Graphical User Interface) applications for the X Window
System.

During a security audit, Chris Evans discovered a heap overflow in the BMP
image decoder in Qt versions prior to 3.3.3. An attacker could create a
carefully crafted BMP file in such a way that it would cause an application
linked with Qt to crash or possibly execute arbitrary code when the file
was opened by a victim. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0691 to this issue.

Additionally, various flaws were discovered in the GIF, XPM, and JPEG
decoders in Qt versions prior to 3.3.3. An attacker could create carefully
crafted image files in such a way that it could cause an application linked
against Qt to crash when the file was opened by a victim. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
names CAN-2004-0692 and CAN-2004-0693 to these issues.

Users of Qt should update to these updated packages which contain
backported patches and are not vulnerable to these issues.
