Fedora: qt buffer overflow (Core 1)

August 23, 2004

During a security audit, Chris Evans discovered a heap overflow in the BMPimage decoder in Qt versions prior to 3.3.3.

Summary

Qt is a GUI software toolkit which simplifies the task of writing and

maintaining GUI (Graphical User Interface) applications

for the X Window System.

Qt is written in C++ and is fully object-oriented.

This package contains the shared library needed to run qt

applications, as well as the README files for qt.

Update Information:

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. * Thu Aug 19 2004 Than Ngo <than@redhat.com> 1:3.1.2-14.2
