8.84. hmaccalc
Updated hmaccalc packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The hmaccalc packages contain tools to calculate HMAC (Hash-based Message Authentication Code) values for files. The names and interfaces were designed to mimic those of the sha1sum, sha256sum, sha384sum and sha512sum tools provided by the coreutils package.
Bug Fix
- BZ#1016706
- The .hmac files are used to check the kernel image at the boot time; if the check fails, the boot process is expected to be halted. Previously, the hmaccalc utility did not flag empty .hmac files as an error, allowing the system to boot even if the boot was supposed to fail. With this update, a patch has been provided to address this bug. As a result, the system is no longer allowed to boot in the described scenario.
Users of hmaccalc are advised to upgrade to these updated packages, which fix this bug.
