Hi
I'm running a svn set-up with a https server that requires client
certificates.
Server: apache 2.2.15 with mod_ssl (2.2.15)
I've updated the server's openssl to 1.0.0a
AFAIS that library implements RFC 5746 (
http://www.ietf.org/rfc/rfc5746.txt ) to solve the CVE-2009-3555 (
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3555 ) unsafe
renegotiation/MITM issue.
TortoiseSVN uses openssl 0.9.8k without RFC 5746
My TortoiseSVN about info:
TortoiseSVN 1.6.8, Build 19260 - 32 Bit , 2010/04/16 20:20:11
Subversion 1.6.11,
apr 1.3.8
apr-utils 1.3.9
neon 0.29.3
OpenSSL 0.9.8k 25 Mar 2009
zlib 1.2.3
When i try to do an update (or anything else that talks to the server)
with TortoiseSVN now it fails according to the RFC:
TortoiseSVN reports
Error: OPTIONS of 'https://<server>/<path>/trunk': Could not read
Error: status line: SSL error: sslv3 alert handshake failure
(https://<server>)
and apache logs

or in short "SSL routines:SSL3_ACCEPT:unsafe legacy renegotiation disabled"
So i'd be really happy if there would be a TortoiseSVN with openssl
0.9.8o (or maybe 0.9.8[m-n]) or openssl 1.0.0a (or 1.0.0)
(And no, i don't want to completely disable renegotiation. I DO want to
allow different certificates on different parts of the server. And the
client can be on the "outside", not just 192.168...)
Best regards, Roland
