mod_gnutls: Certificate validation error

mod_gnutls: Certificate validation error A vulnerability in mod_gnutls allows remote attackers to spoof clients via crafted certificates. mod_gnutls 2017-09-17 2017-09-17 541038 remote 0.7.3 0.7.3

mod_gnutls is an extension for Apache’s httpd. It uses the GnuTLS library to provide HTTPS. It supports some protocols and features that mod_ssl does not.

It was discovered that the authentication hook in mod_gnutls does not validate client’s certificates even when option “GnuTLSClientVerify” is set to “require”.

A remote attacker could present a crafted certificate and spoof clients data.

There is no known workaround at this time.

All mod_gnutls users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=www-apache/mod_gnutls-0.7.3"
