Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : ecryptfs-utils vulnerability (USN-2524-1)
Medium Nessus Plugin ID 81756
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionSylvain Pelissier discovered that eCryptfs did not generate a random salt when encrypting the mount passphrase with the login password. An attacker could use this issue to discover the login password used to protect the mount passphrase and gain unintended access to the encrypted files.
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 ecryptfs-utils and / or libecryptfs0 packages.
