5.190. microcode_ctl

Updated microcode_ctl packages that fix one bug and add two enhancements are now available for Red Hat Enterprise Linux 6.
The microcode_ctl packages provide microcode updates for Intel and AMD processors.

Bug Fix

BZ#768803
Previously, running the microcode_ctl utility with long arguments for the "-d" or "-f" options led to a buffer overflow. Consequently, microcode_ctl terminated unexpectedly with a segmentation fault and a backtrace was displayed. With this update, microcode_ctl has been modified to handle this situation gracefully. The microcode_ctl utility no longer crashes and displays an error message informing the user that the file name used is too long.

Enhancements

BZ#736266
The Intel CPU microcode file has been updated to version 20111110, which is the latest version of the microcode available from Intel.
BZ#787757
The AMD CPU microcode file has been updated to version 20120117, which is the latest version of the microcode available from AMD.
All users of microcode_ctl are advised to upgrade to these updated packages, which fix this bug and add these enhancements.
