Ubuntu 14.04 LTS : eCryptfs vulnerability (USN-2524-1)

critical Nessus Plugin ID 81756

Synopsis

The remote Ubuntu host is missing a security update.

Description

Sylvain 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.

Solution

Update the affected packages.
