hmaccalc bug fix update

Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated hmaccalc package that fixes a bug is now available for Red Hat
Enterprise Linux 5.
Description
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:
- Prior to this update, hmaccalc erroneously truncated the values which it read
from a checkfile before comparing them with the computed values. Consequently,
comparison between differently truncated sums of files passed in some cases.
This update backports a change which modifies the hmaccalc tool so that when it
is used to verify checksums, if it is told to truncate computed values during a
verification operation, it will not truncate the values which it reads from a
checkfile before comparing them with the computed values. As a result hmaccalc
correctly detects differences in hmac values. (BZ#658178).
All users of hmaccalc are advised to upgrade to this updated package, which
fixes this bug.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
