RHBA-2014:1600 - python-kerberos bug fix update

Synopsis

python-kerberos bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated python-kerberos packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The python-kerberos packages contain a high-level wrapper for Kerberos Generic Security Service Application Program Interface (GSSAPI) operations.

This update fixes the following bugs:

  • Previously, the name of the egg-info file contained an incorrect version of the python-kerberos packages. As a consequence, the module dependency resolution did not work correctly. With this update, the egg-info file name contains the correct version, and resolving dependencies works as expected. (BZ#973379)

  • Prior to this update, the authenticate_gss_client_wrap() function miscalculated the length of the username string when wrapping it. Consequently, the Kerberos user name was not properly encoded into a GSSAPI message, and the authentication failed. This patch fixes the calculation of the username string length, and the authentication no longer fails. (BZ#1057333)

Users of python-kerberos are advised to upgrade to these updated packages, which fix these bugs.

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/site/articles/11258
