Description

Andreas Nolden has reported a vulnerability in Qt, which potentially can be exploited to conduct cross-site scripting attacks in applications using the Qt libraries.

The vulnerability is caused due to Qt not properly rejecting overly long UTF-8 character sequences. This can be exploited to bypass certain character sanitation mechanisms and allow e.g. the execution of HTML and script code in applications depending on the correct behavior.

The vulnerability is reported in Qt 3.x and 4.x.


Solution
Apply patches.
