Solution:
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
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 libgnutls.so.1[0-1]
Previously exported RSA keys can be fixed by executing the
following command on the key files:
# certtool -k infile outfile

Network Security Threat Level: Medium
