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

medium Nessus Plugin ID 85429


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

Description 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.


Update the affected package.
