TITLE:
Qt Pixmap Image Handling Integer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA22380

VERIFY ADVISORY:
http://secunia.com/advisories/22380/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
Qt 4.x
http://secunia.com/product/12368/
Qt 3.x
http://secunia.com/product/383/

DESCRIPTION:
A vulnerability has been reported in Qt, which can be exploited by
malicious people to cause a DoS (Denial of Service) and potentially
compromise an application using the library.

The vulnerability is caused due to an integer overflow within the way
Qt handles certain pixmap images. This can potentially be exploited to
execute arbitrary code by e.g. causing an application linked against
Qt to process a specially crafted pixmap image.

SOLUTION:
Do not open untrusted images with applications using the Qt library.
