Description Mark J. Cox 2003-12-02 09:01:32 EST
hong Nguyen identified a severe bug in the way GnuPG creates and uses
ElGamal keys, which can be used for signing. 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 revoke those keys immediately.

The packages included in our upcoming update do not make such keys
safe to use -- they merely include a patch by David Shaw that disables
functions which would generate or use such keys.
