Description:
Maksim Orlovich has reported a vulnerability in KDE kjs, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a user's system.
The vulnerability is caused due to a boundary error in kjs in the decoding of UTF-8 encoded URI sequences. This can be exploited to cause a heap-based buffer overflow by supplying specially crafted JavaScript code via an application using the affected JavaScript interpreter engine (e.g. Konqueror).
Successful exploitation allows execution of arbitrary code.
The vulnerability has been reported in versions 3.2.0 through 3.5.0.
Solution:
Apply patches.
