USN-872-1: KDE 4 Runtime vulnerabilities

Releases

• Ubuntu 9.10
• Ubuntu 9.04
• Ubuntu 8.10

Packages

• kdebase-runtime -

Details

It was discovered that the KIO subsystem of KDE did not properly perform
input validation when processing help:// URIs. If a user or KIO application
processed a crafted help:// URI, an attacker could trigger JavaScript
execution or access files via directory traversal.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10

• kdebase-runtime - 4:4.3.2-0ubuntu4.1

Ubuntu 9.04

• kdebase-runtime - 4:4.2.2-0ubuntu1.1

Ubuntu 8.10

• kdebase-runtime - 4:4.1.4-0ubuntu1~intrepid1.2

After a standard system upgrade you need to restart your session to effect
the necessary changes.
