SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionFlorian Weimer discovered that Sudo incorrectly handled the noexec restriction when used with certain applications. A local attacker could possibly use this issue to bypass configured restrictions and execute arbitrary commands. (CVE-2016-7076)
It was discovered that Sudo did not properly parse the contents of /proc/[pid]/stat when attempting to determine its controlling tty. A local attacker in some configurations could possibly use this to overwrite any file on the filesystem, bypassing intended permissions.
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.
SolutionUpdate the affected sudo and / or sudo-ldap packages.
