Can anyone comment on this recent security advisory, and whether any of
RedHat's patches have been submitted to the gnupg cvs?
Sincerely,

Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated gnupg packages now available
Advisory ID: RHSA-2000:131-02
Issue date: 2000-12-19
Updated on: 2000-12-19
Product: Red Hat Linux
Keywords: gnupg secret-key web-of-trust detached-signature
Cross references:
---------------------------------------------------------------------
1. Topic:
Updated gnupg packages are now available for Red Hat Linux 6.x and 7.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
3. Problem description:
When importing keys from public key servers, GnuPG will import private keys
(also known as secret keys) in addition to public keys. If this happens,
the user's web of trust becomes corrupted. Additionally, when used to check
detached signatures, if the data file being checked contained clearsigned
data, GnuPG would not warn the user if the detached signature was
incorrect.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
21889 - Web of trust circumvention by secret key distribution
21498 - Detached signature verification vulnerability
6. RPMs required:
