Title: Trolltech Qt UTF-8 Sequences Input Validation Vulnerability

Severity: MODERATE

Description:

Trolltech Qt is an application-development framework for the KDE desktop system. It supports windowing, multimedia, and other functionality.

Trolltech Qt is prone to an input-validation vulnerability because it fails to properly sanitize user-supplied input. Specifically, the issue occurs because the application accepts overly long UTF-8 sequences. This may cause applications employing Qt to treat UTF-8-escaped data as non-escaped.

An attacker may leverage this issue to exploit other issues in applications that employ the affected library. A successful attack may allow the attacker to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Qt 3.3.8 and 4.2.3 are known to be vulnerable to this issue; other versions may be affected as well.
