                   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
Product:           Red Hat Linux

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

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
