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.
The Common Vulnerabilities and Exposures (CVE) project has assigned
CVE-2010-1000 for the vulnerability.
