Ubuntu 10.04 LTS / 10.10 / 11.04 : ecryptfs-utils vulnerability (USN-1196-1)

Low Nessus Plugin ID 55968


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


It was discovered that eCryptfs incorrectly handled permissions when modifying the mtab file. A local attacker could use this flaw to manipulate the mtab file, and possibly unmount arbitrary locations, leading to a denial of service.

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.
