Package : gnupg
Vulnerability : cryptographic weakness
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2003-0971

Phong Nguyen identified a severe bug in the way GnuPG creates and uses
ElGamal keys for signing. This is a significant security failure
which can lead to a compromise of almost all ElGamal keys used for
signing.

The update provided in DSA 459-1 disables the use of this type of key,
using an interim fix. This update, DSA 459-2, implements a more
correct and permanent fix provided by David Shaw.

For the current stable distribution (woody) this problem has been
fixed in version 1.0.6-4woody3.

We recommend that you update your gnupg package.
