Description Vincent Danen 2010-05-12 17:54:25 UTC
Secunia Research reported a flaw in KDE KGet that can be used by a malicious attacker to potentially compromise a user's system.  The "name" attribute of the "file" element in metalink files is not properly sanitized before being used to download files.  If a user were tricked into downloading a specially crafted metalink file, it could be used to download files to directories outside of the intended download directory via directory traversal flaws.  KGet will start to download files in the background even before a user confirms whether or not they want the particular file downloaded, which could lead to KGet silently overwriting existing files with the same name.

This flaw has been assigned the name CVE-2010-1000.  It also only affects KGet in KDE 4.x and does not affect earlier versions.  Only Red Hat Enterprise Linux 6 and Fedora would be affected.

Comment 2 Vincent Danen 2010-05-13 14:42:23 UTC
This is now public via Ubuntu's advisory (USN-938-1):

http://lists.grok.org.uk/pipermail/full-disclosure/2010-May/074535.html

I don't see anything from upstream, however.

Comment 3 Jaroslav Reznik 2010-05-13 14:54:05 UTC
Hi Vincent,
yes it's public now - http://kde.org/info/security/advisory-20100513-1.txt.

Comment 4 Vincent Danen 2010-05-13 14:58:30 UTC
Upstream's advisory:

http://www.kde.org/info/security/advisory-20100513-1.txt

It also notes CVE-2010-1511, so they've further split the problem as noted in the description into two issues.  Quoting the upstream advisory:

1) The "name" attribute of the "file" element of metalink files is not
properly sanitized before being used 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. (CVE-2010-1000)

2) In some versions of KGet (2.4.2) a dialog box is displayed allowing the
user to choose the file to download out of the options offered by the
metalink file. However, KGet will simply go ahead and start the download
after some time - even without prior acknowledgment of the user, and
overwriting already-existing files of the same name. (CVE-2010-1511)

The vulnerabilities were reported by and the above text provided by Stefan
Cornelius of Secunia Research.
