5.190. microcode_ctl

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.

The Intel CPU microcode file has been updated to version 20111110, which is the latest version of the microcode available from Intel.

The AMD CPU microcode file has been updated to version 20120117, which is the latest version of the microcode available from AMD.
