RHBA-2013:0405 - Bug Fix Advisory

Topic

Updated python-nss packages that fix several bugs and add various enhancements
are now available for Red Hat Enterprise Linux 6.

Description

The python-nss packages provide bindings for Network Security Services (NSS)
that allow Python programs to use the NSS cryptographic libraries for SSL/TLS
and PKI certificate management.

The python-nss packages have been upgraded to upstream version 0.13, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#827616)

This update also fixes the following bugs:

• On the 64-bit architecture, the setup_certs.py script contained an incorrect

path to the libnssckbi.so library. As a consequence, the script attempted to run
the "modutil -dbdir pki -add ca_certs -libfile /usr/lib/libnssckbi.so" command
and failed with an error, because on this architecture, the libnssckbi.so
library is located in the /usr/lib64/ directory. This update allows the modutil
command-line utility to find the libnssckbi.so module based on its knowledge of
the system. (BZ#698663)

• When setting Basic Constraints for a CA certificate, the python-nss package

failed with the following message:

cannot decode Basic Constraints

This was because of an incorrect format specifier, which is now fixed and
python-nss no longer fails in this scenario. (BZ#796295)

In addition, this update adds the following enhancement:

• The python-nss package has been updated to add support for PKCS#12 files.

(BZ#642795)

Users of python-nss are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.

Solution

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

This update is available via the Red Hat Network. Details on how to
