RHBA-2013:0405 - python-nss bug fix and enhancement update

Synopsis

python-nss bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

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 use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
