Synopsis =3D=3D=3D=3D=3D=3D=3D=3D
A vulnerability in mod_gnutls allows remote attackers to spoof clients via crafted certificates.
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"
