VuXML ID ec6a2a1e-429d-11e5-9daa-14dae9d210b8

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.
