Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : ecryptfs-utils vulnerability (USN-2876-1)

Medium Nessus Plugin ID 88040


The remote Ubuntu host is missing a security-related patch.


Jann Horn discovered that mount.ecryptfs_private would mount over certain directories in the proc filesystem. A local attacker could use this to escalate their privileges. (CVE-2016-1572).

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.


Update the affected ecryptfs-utils package.
