Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D mod_gnutls is an extension for =E2=80=8BApache's httpd. It uses the =E2=80= =8BGnuTLS library to provide HTTPS. It supports some protocols and features that mod_ssl does not. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_gnutls < 0.7.3 >=3D 0.7.3=20 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D It was discovered that the authentication hook in mod_gnutls does not validate client's certificates even when option "GnuTLSClientVerify" is set to "require". Impact =3D=3D=3D=3D=3D=3D A remote attacker could present a crafted certificate and spoof clients data. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All mod_gnutls users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Dwww-apache/mod_gnutls-0.7.3" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2015-2091 https://nvd.nist.gov/nvd.cfm?cvename=3DCVE-2015-2091 Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201709-04 Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
