 =========================================================== 
Ubuntu Security Notice USN-436-2               May 18, 2007
ktorrent vulnerability
CVE-2007-1799
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 6.06 LTS:
  ktorrent                                 1.2-0ubuntu5.2

Ubuntu 6.10:
  ktorrent                                 2.0.3+dfsg1-0ubuntu1.2

Ubuntu 7.04:
  ktorrent                                 2.1-0ubuntu2.1

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

Details follow:

USN-436-1 fixed a vulnerability in KTorrent.  The original fix for path 
traversal was incomplete, allowing for alternate vectors of attack.  
This update solves the problem.

Original advisory details:

 Bryan Burns of Juniper Networks discovered that KTorrent did not 
 correctly validate the destination file paths nor the HAVE statements 
 sent by torrent peers. A malicious remote peer could send specially 
 crafted messages to overwrite files or execute arbitrary code with user 
 privileges.
