Red Hat Linux Advisory: gnupg

Red Hat Security Advisory

1. Topic:

Updated gnupg packages correcting a bug in the GnuPG key
validation functions are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.1 – i386
Red Hat Linux 7.2 – i386, ia64
Red Hat Linux 7.3 – i386
Red Hat Linux 8.0 – i386
Red Hat Linux 9 – i386

3. Problem description:

The GNU Privacy Guard (GnuPG) is a utility for encrypting data
and creating digital signatures.

When evaluating trust values for different UIDs assigned to a
given key, GnuPG versions earlier than 1.2.2 would incorrectly
associate the trust value of the UID with the highest trust value
with every UID assigned to that key. This would prevent an expected
warning message from being generated.

All users are advised to upgrade to these errata packages which
include patches from the GnuPG development team that correct this
issue for GnuPG versions 1.0.7 and 1.2.1. This update also upgrades
Red Hat Linux 7.1, 7.2, and 7.3 users to GnuPG version 1.0.7.

4. Solution:

Before applying this update, make sure all previously released
errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.
Only those RPMs which are currently installed will be updated.
Those RPMs which are not installed but included in the list will
not be updated. Note that you can also use wildcards (*.rpm) if
your current directory only contains the desired RPMs.

Please note that this update is also available via Red Hat
Network. Many people find this an easier way to apply updates. To
use Red Hat Network, launch the Red Hat Update Agent with the
following command:

up2date

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.

6. Verification:

These packages are GPG signed by Red Hat for security. Our key
is available at http://www.redhat.com/solutions/security/news/publickey/

You can verify each package with the following command:

    rpm --checksig -v <filename>

If you only wish to verify that each package has not been
corrupted or tampered with, examine only the md5sum with the
following command:

    md5sum <filename>
