Title: mod_gnutls: Certificate validation error (GLSA 201709-04)
A vulnerability in mod_gnutls allows remote attackers to spoof
clients via crafted certificates.
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.
Vulnerable: < 0.7.3
Unaffected: >= 0.7.3
Architectures: All supported architectures
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
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"
