Chapter 1. Package Updates

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

Abstract Machine Test Utility (AMTU) is an administrative utility to check whether the underlying protection mechanism of the hardware are still being enforced. This is a requirement of the Controlled Access Protection Profile FPT_AMT.1.

This update fixes the following bug:

* Previously, the amtu memory separation test could fail randomly because the way that it chose memory regions for testing had an off by one error in the address calculation. The memory separation test tries to locate memory regions that are readonly. Because of the miscalculation, it could try writing to a memory location that was writable. Because it was looking for the write to fail, it mistakenly thinks the test had failed. This update corrects this issue and the amtu memory separation test behaves as expected. ( BZ#556853)

All amtu users are advised to upgrade to this updated package, which resolves this issue.
