Descriptions

The UTF-8 decoder in codecs/qutfcodec.cpp in Qt 3.3.8 and 4.2.3 does not reject long UTF-8 sequences as required by the standard, which allows remote attackers to conduct cross-site scripting (XSS) and directory traversal attacks via long sequences that decode to dangerous metacharacters.

El decodificador de UTF-8 en el codecs/qutfcodec.cpp del Qt 3.3.8 y 4.2.3 no rechaza secuencias largas de UTF-8 como lo solicitado por el estándar, lo que permite a atacantes remotos llevar a cabo ataques de secuencias de comandos en sitios cruzados (XSS) y de escalado de directorios mediante secuencias largas que decodifican metacaracteres peligrosos.
