RHBA-2011:1589 - python-dmidecode bug fix update

Synopsis

python-dmidecode bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated python-dmidecode package that fixes various bugs 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.

The python-dmidecode package has been upgraded to upstream version 3.10.13, which provides a number of bug fixes over the previous version. (BZ#621567)

This updated python-dmidecode package includes fixes for the following bugs:

  • When trying to identify the processor type by performing a string comparison, Python terminated with a segmentation fault. This was caused by DMI tables which did not report the CPU processor information as a string and returned a NULL value instead. This update adds additional checks for NULL values before doing the string comparison. (BZ#627901)

  • Previously, when calling the memcpy() function on the IBM System z machine which was under heavy memory load, a SIGILL signal was triggered. As a consequence, the complete Python interpreter core dumped. A signal handler was added to properly handle heavy memory loads. (BZ#646429)

  • Prior to this update, when running the rhn_register utility, providing a valid user name and password, and clicking the Forward button, the tool terminated unexpectedly with a segmentation fault. This was caused by the dmi_processor_id() function not checking whether the version pointer was NULL. This update adds additional checks for NULL values, fixing the problem. (BZ#667363)

All users of python-dmidecode are advised to upgrade to this updated package, which resolves these bugs.
