FreeBSD : gnutls -- double free in certificate DN decoding (ec6a2a1e-429d-11e5-9daa-14dae9d210b8)

Synopsis :

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

Description :

gnutls.org reports :

Kurt Roeckx reported that decoding a specific certificate with very
long DistinguishedName (DN) entries leads to double free, which may
result to a denial of service. Since the DN decoding occurs in almost
all applications using certificates it is recommended to upgrade the
latest GnuTLS version fixing the issue. Recommendation: Upgrade to
GnuTLS 3.4.4, or 3.3.17.
