Subject: [RHSA-2000:131-02] Updated gnupg packages now
available
Red Hat, Inc. 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
