cms, ocsp, s_client, s_server and smime tools also use args_verify()
for parsing options, that makes them most of the same options
verify tool does. Add those options to man pages and reference
their explanation in the verify man page.
The options related to policy used for verification, verification
of subject names in certificate and certificate chain handling
were missing in the verify(1) man page. This fixes this issue.
Allow CCS after finished has been sent by client: at this point
keys have been correctly set up so it is OK to accept CCS from
server. Without this renegotiation can sometimes fail.
PR#3400
A client reference identity of ".example.com" matches a server
certificate presented identity that is any sub-domain of "example.com"
(e.g. "www.sub.example.com).
With the X509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS flag, it matches
only direct child sub-domains (e.g. "www.sub.example.com").
* Make a clear distinction between DH and ECDH key exchange.
* Group all key exchange cipher suite identifiers, first DH then ECDH
* add descriptions for all supported *DH* identifiers
* add ECDSA authentication descriptions
* add example showing how to disable all suites that offer no
authentication or encryption
Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.
Because of a missing include <fcntl.h> we don't have O_CREATE and don't create
the file with open() using mode 0600 but fall back to using fopen() with the
default umask followed by a chmod().
Problem found by Jakub Wilk <jwilk@debian.org>.
A buffer overrun attack can be triggered by sending invalid DTLS fragments
to an OpenSSL DTLS client or server. This is potentially exploitable to
run arbitrary code on a vulnerable client or server.
Fixed by adding consistency check for DTLS fragments.
Thanks to Jüri Aedla for reporting this issue.
