CVE-2009-1417

from Debian: "[lenny] - gnutls26 <no-dsa> (Minor issue, explicitly
labeled as a test program)"
from upstream: "We are concerned that changing the semantics of an
existing function in this way may be seen as backwards incompatible, but we
believe having a default-secure mode should carry more weight here."
problem is that while gnutls-cli does report the expiration
properly, it does not exit with error if the certificate is not active
or expired. The upstream patches are not backwards compatible and the
risk of regression in changing the library far outweighs the security
benefit of applying this patch to adjust the return code for gnutls-bin.
It is possible to adjust the return code of gnutls-bin, but this would
require diverging from upstream and causing maintenance problems down the
road.
