======================================================================
4) Description of Vulnerability

Secunia Research has discovered a vulnerability in KDE, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to KGet not properly sanitising 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.

======================================================================
5) Solution

Apply patches for the 4.3 and 4.4 branches committed to the KDE
Subversion repository.
