There is a vulnerability in KDE kjs JavaScript interpreter engine which
can be exploited to cause a DoS or arbitrary code to be executed on a
vulnerable system.

The JavaScript interpreter engine used by Konqueror and other parts of
KDE contain a heap overflow which can be triggered when decoding
specially crafted UTF-8 encoded URI sequences. Vulnerable system can be
compromised by malicious javascript code (e.g. on a malicious website)
using affected JavaScript interpreter engine.
