Ubuntu Security Notice USN-725-1
26th February, 2009
kdepim vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.10
- Ubuntu 8.04 LTS
- Ubuntu 7.10
- Ubuntu 6.06 LTS
Software description
- kdepim
Details
It was discovered that Kmail did not adequately prevent execution of arbitrary
code when a user clicked on a URL to an executable within an HTML mail. If a
user clicked on a malicious URL and chose to execute the file, a remote
attacker could execute arbitrary code with user privileges. This update changes
KMail's behavior to instead launch a helper program to view the file if the
user chooses to execute such a link.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 8.10:
- kmail 4:4.1.4-0ubuntu1~intrepid2.1
- Ubuntu 8.04 LTS:
- kmail 4:3.5.10-0ubuntu1~hardy3.1
- Ubuntu 7.10:
- kmail 4:3.5.7enterprise20070926-0ubuntu2.2
- Ubuntu 6.06 LTS:
- kmail 4:3.5.2-0ubuntu6.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart KMail to effect
the necessary changes.
