Ubuntu 6.06 LTS / 6.10 / 7.04 : ktorrent vulnerability (USN-436-2)

Ubuntu Security Notice (C) 2007-2015 Canonical, Inc. / NASL script (C) 2007-2015 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

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.

Solution :

Update the affected ktorrent package.

Risk factor :

Medium / CVSS Base Score : 6.4
(CVSS2#AV:N/AC:L/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
