As noted by Ludwig Nussel of the SUSE security team, w3m does not, by default, verify certificates, however the /etc/w3m/config configuration as supplied by Red Hat Enterprise Linux 5 and Fedora, do have "ssl_verify_server 1" set, so w3m is doing certificate verification by default.

patch to force ssl_verify_server on and disable SSLv2 support
Patch provided by Ludwig Nussel from the SUSE security team. We don't necessarily need this to enable SSL verification as we do that already, however this patch also disables the use of SSLv2 which we may want.
