Severity:	normal
Title:	KDE kjs: URI heap overflow vulnerability
Date:	01/22/2006
Bugs:	#118550
ID:	200601-11

Synopsis

KDE fails to properly validate URIs when handling javascript, potentially resulting in the execution of arbitrary code.

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. kjs is the javascript interpreter used in Konqueror and other parts of KDE.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-base/kdelibs	< 3.4.3-r1	>= 3.4.3-r1	All supported architectures

Description

Maksim Orlovich discovered an incorrect bounds check in kjs when handling URIs.

Impact

By enticing a user to load a specially crafted webpage containing malicious javascript, an attacker could execute arbitrary code with the rights of the user running kjs.

Workaround

There is no known workaround at this time.

Resolution

All kdelibs users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/kdelibs-3.4.3-r1
