Posted on: 06/08/2009 10:15 PM

A new eCryptfs vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-783-1 June 08, 2009
ecryptfs-utils vulnerability

A security issue affects the following Ubuntu releases:

Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 9.04:
ecryptfs-utils 73-0ubuntu6.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Chris Jones discovered that the eCryptfs support utilities would
report the mount passphrase into installation logs when an eCryptfs
home directory was selected during Ubuntu installation. The logs are
only readable by the root user, but this still left the mount passphrase
unencrypted on disk, potentially leading to a loss of privacy.
