Description

Tavis Ormandy, Julien Tinnes, and Yorick Koster discovered that PulseAudio did not safely re-execute itself. A local attacker could exploit this to gain root 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.
