A race condition has been discovered in the file permission handling of the /proc file system. A local attacker could exploit this to execute arbitrary code with full 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.
