Title:
  12.04/openssl refusing some verisign certified sites

Status in OpenSSL cryptography and SSL/TLS toolkit:
  Unknown
Status in “openssl” package in Ubuntu:
  Confirmed

Bug description:
  After upgrading a 10.04 server to 12.04, SSL refuses to work with some sites.
  On 10.04,
  curl -v https://cs.directnet.com/dn/c/cls/auth?language=de
  works fine, on 12.04 it says:
  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

  This happens on some very well know bank sites , another example is https://postfinance.ch.
  Hence I think

  Analysis:
  - test on an 10.04 upgraded to 12.04 and also a 12.04 fresh server installation
  - curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3
  - Calling ssl directly:
  openssl s_client -host cs.directnet.com -port 443
   says "self signed certificate in certificate chain", and the chain shown is:

  Certificate chain
   0 s:/1.3.6.1.4.1.311.60.2.1.3=CH/businessCategory=Private Organization/serialNumber=CH-020.3.906.075-9/C=CH/postalCode=8001/ST=Zuerich/L=Zuerich/street=Paradeplatz 8/O=Credit Suisse Group AG/CN=cs.directnet.com

     i:/C=US/O=VeriSign, Inc./OU=Class 3 Public Primary Certification Authority

  Now there are lots of certificates in /usr/share/ca-
  certificates/mozilla (148 of them, there were 123 in Lucid 10.04).

  Search the existing openssl/12.04 issues I came across ciper issues, but didnt' notice a bus for certs.
  Since this affects well know sites it would seems to be quite an important issue?
