Ubuntu 10.10 / 11.04 / 11.10 : software-center vulnerability (USN-1270-1)

Medium Nessus Plugin ID 56912


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


David B. discovered that Software Center incorrectly validated server certificates when performing secure connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information or install altered packages and repositories.

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.


Update the affected software-center package.
