Fedora Core 1 : gnupg-1.2.3-2 (2003-025)

This script is Copyright (C) 2004-2015 Tenable Network Security, Inc.


Synopsis :

The remote Fedora Core host is missing a security update.

Description :

Phong Nguyen identified a severe bug in the way GnuPG creates and uses
ElGamal keys, when those keys are used both to sign and encrypt data.
This vulnerability can be used to trivially recover the private key.
While the default behavior of GnuPG when generating keys does not lead
to the creation of unsafe keys, by overriding the default settings an
unsafe key could have been created.

If you are using ElGamal keys, you should revoke those keys
immediately.

The packages included in this update do not make ElGamal keys safe to
use; they merely include a patch by David Shaw that disables functions
that would generate or use ElGamal keys for encryption.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
