Description

Marc Deslauriers discovered that system-config-printer's cupshelpers scripts used by the Ubuntu automatic printer driver download service queried the OpenPrinting database using an insecure connection. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to 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.
