Konqueror: Java sandbox vulnerabilities — GLSA 200501-16

The Java sandbox environment in Konqueror can be bypassed to access arbitrary packages, allowing untrusted Java applets to perform unrestricted actions on the host system.

Affected packages

Package 	kde-base/kdelibs on all architectures
Affected versions 	< 3.3.2
Unaffected versions 	>= 3.3.2

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. Konqueror is the KDE web browser and file manager.

Description

Konqueror contains two errors that allow JavaScript scripts and Java applets to have access to restricted Java classes.

Impact

A remote attacker could embed a malicious Java applet in a web page and entice a victim to view it. This applet can then bypass security restrictions and execute any command, or access any file with the rights of the user running Konqueror.

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
