FreeBSD : gnupg -- false positive signature verification (63fe4189-9f97-11da-ac32-0001020eed82)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Werner Koch reports :

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 problem affects the tool *gpgv*, as well as using 'gpg --verify'
to imitate gpgv, if only the exit code of the process is used to
decide whether a detached signature is valid. This is a plausible mode
of operation for gpgv.

If, as suggested, the --status-fd generated output is used to decide
whether a signature is valid, no problem exists. In particular
applications making use of the GPGME library[2] are not affected.
