GnuTLS is a free TLS 1.0 and SSL 3.0 implementation for the GNU
A vulnerability has been discovered in the record packet parsing
in the GnuTLS library. Additionally, a flaw was also found in the RSA
key export functionality.
<impact type="normal">
A remote attacker could exploit this vulnerability and cause a
Denial of Service to any application that utilizes the GnuTLS library.
There is no known workaround at this time.
All GnuTLS users should remove the existing installation and
upgrade to the latest version:
# emerge --sync
# emerge --unmerge gnutls
# emerge --ask --oneshot --verbose net-libs/gnutls</code>
Due to small API changes with the previous version, please do
the following to ensure your applications are using the latest GnuTLS
that you just emerged.
# revdep-rebuild --soname-regexp[0-1]</code>
Previously exported RSA keys can be fixed by executing the
following command on the key files:
# certtool -k infile outfile</code>
