                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated gnupg packages available
Advisory ID:       RHSA-2001:063-02
Issue date:        2001-05-02
Updated on:        2001-05-16

---------------------------------------------------------------------

1. Topic:

Updated gnupg packages are now available for Red Hat Linux 6.2, 7, and 7.1.
 These updates address a potential vulnerability which could allow an
attacker to compute a user's secret key.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - i386

3. Problem description:

By modifying an unsuspecting user's private keyring, an attacker can cause
a user to generate incorrect signatures for data.  If a user generates both
a correct and an incorrect signature for the same data, the different
signatures can be used to compute the user's secret key.

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.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

33473 - secret keyring compromise leading to secret key disclosure
