These updated ecryptfs-utils packages have been upgraded to upstream version 75, which provides a number of bug fixes and enhancements over the previous version. In addition, these packages provide a graphical program to help configure and use eCryptfs. To start this program, run the command :
ecryptfs-mount-helper-gui
Important: the syntax of certain eCryptfs mount options has changed.
Users who were previously using the initial Technology Preview release of ecryptfs-utils are advised to refer to the ecryptfs(7) man page, and to update any affected mount scripts and /etc/fstab entries for eCryptfs file systems.
A disclosure flaw was found in the way the ‘ecryptfs-setup-private’ script passed passphrases to the ‘ecryptfs-wrap-passphrase’ and ‘ecryptfs-add-passphrase’ commands as command line arguments. A local user could obtain the passphrases of other users who were running the script from the process listing. (CVE-2008-5188)
These updated packages provide various enhancements, including a mount helper and supporting libraries to perform key management and mounting functions.
Notable enhancements include :
a new package, ecryptfs-utils-gui, has been added to this update. This package depends on the pygtk2 and pygtk2-libglade packages and provides the eCryptfs Mount Helper GUI program. To install the GUI, first install ecryptfs-utils and then issue the following command :
yum install ecryptfs-utils-gui
(BZ#500997)
the ‘ecryptfs-rewrite-file’ utility is now more intelligent when dealing with non-existent files and with filtering special files such as the ‘.’ directory.
In addition, the progress output from ‘ecryptfs-rewrite-file’ has been improved and is now more explicit about the success status of each target.
(BZ#500813)
descriptions of the ‘verbose’ flag and the ‘verbosity=[x]’ option, where [x] is either 0 or 1, were missing from a number of eCryptfs manual pages, and have been added. Refer to the eCryptfs man pages for important information regarding using the verbose and/or verbosity options. (BZ#470444)
These updated packages also fix the following bugs :
mounting a directory using the eCryptfs mount helper with an RSA key that was too small did not allow the eCryptfs mount helper to encrypt the entire key. When this situation occurred, the mount helper did not display an error message alerting the user to the fact that the key size was too small, possibly leading to corrupted files. The eCryptfs mount helper now refuses RSA keys which are to small to encrypt the eCryptfs key.
(BZ#499175)
when standard input was redirected from /dev/null or was unavailable, attempting to mount a directory with the eCryptfs mount helper caused it to become unresponsive and eventually crash, or an ‘invalid value’ error message, depending on if the ‘–verbosity=[value]’ option was provided as an argument, and, if so, its value. With these updated packages, attempting to mount a directory using ‘mount.ecryptfs’ under the same conditions results in either the mount helper attempting to use default values (if ‘verbosity=0’ is supplied), or an ‘invalid value’ error message (instead of the mount helper hanging) if standard input is redirected and ‘–verbosity=1’ is supplied, or that option is omitted entirely. (BZ#499367)
attempting to use the eCryptfs mount helper with an OpenSSL key when the keyring did not contain enough space for the key resulted in an unhelpful error message. The user is now alerted when this situation occurs. (BZ#501460)
the eCryptfs mount helper no longer fails upon receiving an incorrect or empty answer to ‘yes/no’ questions.
