Description

Gabriel Campana discovered that Apport incorrectly handled Python module imports. A local attacker could use this issue to elevate privileges.

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.
