Ubuntu 12.04 LTS : ubiquity-slideshow-ubuntu vulnerability (USN-1561-1)
Medium Nessus Plugin ID 62039
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionPaul 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.
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.
SolutionUpdate the affected ubiquity-slideshow-ubuntu package.
