Trolltech Qt UTF-8 Sequences Input Validation Vulnerability

Trolltech Qt UTF-8 Sequences Input Validation Vulnerability

Trolltech Qt is prone to an input-validation vulnerability because the application fails to properly sanitize user-supplied input.

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.
