1.69.1. RHBA-2010:0055: bug fix update
Note
This update has already been released (prior to the GA of this release) as FASTRACK errata RHBA-2010:0055
The hmaccalc package contains 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.
This updated hmaccalc package fixes the following bug:
* each time one of the tools in the hmaccalc package is used, it performs a self-test by comparing the checksum of its own binary with the value which was computed when the binary package was built. However, if an hmaccalc binary had been prelinked using the "prelink" command, and that command was not located in one of the directories listed in the PATH environment variable, then that binary would be unable to use the prelink tool to verify the checksum against an unmodified copy of itself. This update contains a backported fix that allows hmaccalc to remember the location of the prelink command that was available at build time, and to be able to use it if necessary.
Note that this fix is required in order to build the Linux kernel with FIPS-compliance (Federal Information Processing Standards) enabled. (BZ#512275)
All users of hmaccalc are advised to upgrade to this updated package, which resolves this issue.
