RHBA-2011:1688 - Bug Fix Advisory

Topic

Updated cryptsetup-luks packages that fix several bugs and add an enhancement
are now available for Red Hat Enterprise Linux 6.

Description

The cryptsetup-luks packages provide a utility which allows users to set up
encrypted devices with the Device Mapper and the dm-crypt target.

This update fixes the following bugs:

• When the cryptsetup or libcryptsetup utility was run in FIPS (Federal

Information Processing Standards) mode, the "Running in FIPS mode." message was
displayed during initialization of all commands. This sometimes caused minor
issues with associated scripts. This bug has been fixed and the message is now
displayed only in verbose mode. (BZ#713410)

• Prior to this update, several directives were missing in cryptsetup status

command implementation. Therefore, the cryptsetup status command always returned
the exit code 0 when verifying the status of a mapped device. To fix this issue,
the code has been modified. The cryptsetup status command now returns the 0
value only if the device checked is active. (BZ#732179)

This update also provides the following enhancement:

• Previously, the libcryptsetup crypt_get_volume_key() function allowed to

perform an action not compliant with FIPS. To conform FIPS requirements, the
function is now disabled in FIPS mode and returns an EACCES error code to
indicate it. Note that the "luksDump --dump-master-key" command and the key
escrow functionality of the volume_key package are also disabled in FIPS mode as
a consequence of this update. (BZ#701936)

All users of cryptsetup-luks are advised to upgrade to these updated packages,
which fix these bugs and add this enhancement.
