USN-1561-1: ubiquity-slideshow-ubuntu vulnerability

10 September 2012

ubiquity-slideshow-ubuntu would allow unintended access to files over the network during system installation.




Paul Mutton discovered that ubiquity-slideshow-ubuntu incorrectly handled
the Twitter feed displayed during system installation. A remote attacker
could use this flaw to inject code into the Twitter feed and read arbitrary
files off the filesystem during system installation. This flaw has been
resolved in the Ubuntu 12.04.1 LTS installation images by disabling the
Twitter feed.

Update instructions

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

Ubuntu 12.04

Use of the Ubuntu 12.04.1 LTS installation images is required to resolve
this issue.
