Details

An updated mcelog package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

The mcelog package contains a daemon that collects and decodes Machine Check
Exception (MCE) data on AMD64 and Intel 64 machines.

* On some systems, mcelog was able to read beyond the last page of the SMBIOS
tables. This caused a failure in the mmap() call, the "Cannot mmap SMBIOS
tables" error message was issued and the user was unable to run mcelog further.
Now, the range for the mmap() calls has been lowered and the bug no longer
occurs. (BZ#698122)

Users of mcelog are advised to upgrade to this updated package, which fixes this
bug.
