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

medium Nessus Plugin ID 28032

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ktorrent package.
