Public bug reported:

Binary package hint: openssl

Reported intermittent SSL connection issue on some apache mod_ssl
vhosts.

Platform:  Ubuntu 10.04.2 LTS
Tested: Apache2-2.2.14-5ubuntu8.4 and backported 2.2.17-1ubuntu1 from Natty

Firefox client will intermittently report:
Secure Connection Failed
An error occurred during a connection to oem-ibs.canonical.com.
Peer's certificate has an invalid signature.
(Error code: sec_error_bad_signature)

Condition will clear on reload.

Occassionally the server will alternately serve a good page followed by
an SSL error until Apache is restarted. I am unable to reproduce the
condition on demand, but have output from when the fault occurs. When
the fault condition occurs it can be reproduced with any SSL client.

The fault presents on multiple distinct servers.

Initially suspected to be a bug with mod_ssl
https://issues.apache.org/bugzilla/show_bug.cgi?id=46952, backport has
eliminated this as has anecdotal reports of this same error presented
from Dovecot.

Tested with SSL certs from different CAs.

Example:

$ openssl s_client -connect oem-ibs.canonical.com:443
CONNECTED(00000003)
depth=2 /C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c) 2006 
thawte, Inc. - For authorized use only/CN=thawte Primary Root CA
