Ubuntu 14.04 LTS : sudo vulnerability (USN-3968-2)

high Nessus Plugin ID 125593

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-3968-1 fixed a vulnerability in Sudo. This update provides the corresponding update for Ubuntu 14.04 ESM.

Original advisory details :

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.
(CVE-2017-1000368).

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.

Solution

Update the affected sudo and / or sudo-ldap packages.
