RHBA-2011:1156 - Bug Fix Advisory

Topic

An updated python-dmidecode package that fixes a bug is now available for Red
Hat Enterprise Linux 6.

Description

The python-dmidecode package provides a Python extension module that uses the
code-base of the dmidecode utility and presents the data as Python data
structures or as XML data using the libxml2 library.

This update fixes for the following bug:

• Previously, certain DMI (Direct Media Interface) tables did not report CPU

information as a string and returned the NULL value instead. Consequently,
Python terminated unexpectedly with a segmentation fault when trying to identify
the CPU type by performing a string comparison. With this update, additional
checks for NULL values, performed prior the string comparison, have been added
to the code, thus fixing this bug. (BZ#726614)

All users of python-dmidecode are advised to upgrade to this updated package,
which fixes this bug.

Solution

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