Summary0004259: Apache blocking MSIE with "SSL3_ACCEPT:unsafe legacy renegotiation disabled"
DescriptionHi there

We have a webapp that uses client certificates via

<Location ~ "/(ssl_secure/)">
        SSLVerifyClient require
        SSLVerifyDepth 1
        SSLOptions +StrictRequire +StdEnvVars -ExportCertData +OptRenegotiate

This has worked fine for years - until this week when httpd-2.0.52-41.ent.7.centos4 came out. At that moment, all our MSIE7/8 users were locked out. Every time they attempted to access a client-cert protected area, they got the crappy MSIE error page and the Apache error_log reported

[Thu Apr 01 12:41:41 2010] [error] SSL Library Error: 336068931
error:14080143:SSL routines:SSL3_ACCEPT:unsafe legacy renegotiation disabled

Firefox-3.5+ and Chrome work just fine - only MSIE is affected.



TagsNo tags attached.

Actually I've just created the same config on a CentOS-5.3 server running httpd-2.2.3-31.el5.centos.4 and I get the same thing. MSIE doesn't work (fully patched today) but FF and Chrome work

You can close this - I found the underlying issue

It appears as of April 1st 2010, fully patched MSIE still doesn't support the new "renegotiation" SSL options, and so BREAKS with mod_ssl doing client-cert access control.

Until it is fixed, the following mod_ssl option will re-enable MSIE to work - at the cost of increasing compromise risk
