RHBA-2015:0669 - Bug Fix Advisory

Topic

Updated crash packages that fix one bug are now available for Red Hat Enterprise
Linux 5.

Description

The crash packages provide the core analysis suite, which is a self-contained
tool that can be used to investigate live systems, kernel core dumps created
from the netdump, diskdump and kdump packages from Red Hat Linux, as well as the
mcore kernel patch offered by Mission Critical Linux, or the LKCD kernel patch.

This update fixes the following bug:

• Kernel CVE-2014-9322 removed the stackfault exception stack, which in turn

caused the crash utility to generate incorrect backtraces for any active tasks
whose backtrace started from a kernel exception stack. A patch has been provided
to fix this bug, and crash now produces valid backtraces. (BZ#1192396)

Users of crash are advised to upgrade to these updated packages, which fix this
bug.
