Description Josh Bressers 2006-03-01 13:56:21 UTC

+++ This bug was initially created as a clone of Bug #181822 +++

The Gentoo project identified a security related bug in GnuPG.  When
using any current version of GnuPG for unattended signature
verification (e.g. by scripts and mail programs), false positive
signature verification of detached signatures may occur.

This is primarily an issue since gpg return 0 on what should be a failure.  This
will break automated scripts.
