I am happy to announce GnuTLS 1.4.4, a bugfix release on the stable
1.4 branch.  This version is what we recommend for those who need a
stable version of GnuTLS.

GnuTLS is a modern C library that implement the standard network
security protocol Transport Layer Security (TLS), for use by network

Noteworthy changes since 1.4.3:

** Relax the test that caught signatures that exploit the variant of
** Bleichenbacher's Crypto 06 rump session attack on our
** verification logic flaw.
In particular, we now permit the digestAlgorithm.parameters field to
be present but empty, whereas in 1.4.3 we actually checked that the
field was absent.

** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
The messages are only printed in debug mode, which is not recommended
for normal use, and thus logging this situation cannot be abused as an
oracle in typical recommended situations.

Note that this release does not contain any security fixes compared to
1.4.3, however, it does fix a crash that was introduced by 1.4.3, and
it also fixes false negatives when verifying certificates.  Thus,
users are strongly encouraged to upgrade to this version.

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.
