Description


A vulnerability has been reported in KDE, which can be exploited by malicious people to compromise a user's system.

KGet does not properly sanitise the "name" attribute of the "file" element of metalink files before using it to download files. If a user is tricked into downloading from a specially crafted metalink file, this can be exploited to download files to directories outside of the intended download directory via directory traversal attacks.

Note: This is caused due to an incomplete fix for SA39528.

The vulnerability is reported in version 4.6.2. Other versions may also be affected.


Solution:
Fixed in the SVN repository.
