RHEA-2012:0484 - Product Enhancement Advisory

Topic

Updated libgcrypt packages that add one enhancement are now available for Red
Hat Enterprise Linux 5.

Description

The libgcrypt library provides general-purpose implementations of various
cryptographic algorithms.

This update adds the following enhancement:

• With Federal Information Processing Standards (FIPS) mode enabled, the

libgcrypt library always started in the soft FIPS mode which allows applications
to use the MD5 cryptographic hash algorithm. The libgcrypt API previously did
not allow the library to programmatically switch from the soft FIPS mode to the
enforced FIPS mode. With this update, if the application does not need MD5
support for the Transport Layer Security (TLS) protocol or non-cryptographic
purposes, libgcrypt can be preset in the enforced FIPS mode. (BZ#810319)

All users of libgcrypt are advised to upgrade to these updated packages, which
add this enhancement.

Solution

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
