2016-03-07Rework the default cipherlist.Emilia Kasper
- Always prefer forward-secure handshakes. - Consistently order ECDSA above RSA. - Next, always prefer AEADs to non-AEADs, irrespective of strength. - Within AEADs, prefer GCM > CHACHA > CCM for a given strength. - Prefer TLS v1.2 ciphers to legacy ciphers. - Remove rarely used DSS, IDEA, SEED, CAMELLIA, CCM from the default list to reduce ClientHello bloat.

2016-03-04Don't build RC4 ciphersuites into libssl by defaultMatt Caswell
RC4 based ciphersuites in libssl have been disabled by default. They can be added back by building OpenSSL with the "enable-weak-ssl-ciphers" Configure option at compile time. Reviewed-by: Rich Salz <rsalz@openssl.org>
2016-03-03Refactor ClientHello extension parsingEmilia Kasper
1) Simplify code with better PACKET methods. 2) Make broken SNI parsing explicit. SNI was intended to be extensible to new name types but RFC 4366 defined the syntax inextensibly, and OpenSSL has never parsed SNI in a way that would allow adding a new name type. RFC 6066 fixed the definition but due to broken implementations being widespread, it appears impossible to ever extend SNI. 3) Annotate resumption behaviour. OpenSSL doesn't currently handle all extensions correctly upon resumption. Annotate for further clean-up. 4) Send an alert on ALPN protocol mismatch. Reviewed-by: Kurt Roeckx <kurt@openssl.org>

2016-02-25CVE-2016-0798: avoid memory leak in SRPEmilia Kasper
The SRP user database lookup method SRP_VBASE_get_by_user had confusing memory management semantics; the returned pointer was sometimes newly allocated, and sometimes owned by the callee. The calling code has no way of distinguishing these two cases. Specifically, SRP servers that configure a secret seed to hide valid login information are vulnerable to a memory leak: an attacker connecting with an invalid username can cause a memory leak of around 300 bytes per connection. Servers that do not configure SRP, or configure SRP but do not configure a seed are not vulnerable. In Apache, the seed directive is known as SSLSRPUnknownUserSeed. To mitigate the memory leak, the seed handling in SRP_VBASE_get_by_user is now disabled even if the user has configured a seed. Applications are advised to migrate to SRP_VBASE_get1_by_user. However, note that OpenSSL makes no strong guarantees about the indistinguishability of valid and invalid logins. In particular, computations are currently not carried out in constant time.

2016-02-12Rename INSTALL_PREFIX to DESTDIR, remove option --install_prefixRichard Levitte
INSTALL_PREFIX is a confusing name, as there's also --prefix. Instead, tag along with the rest of the open source world and adopt the Makefile variable DESTDIR to designate the desired staging directory. The Configure option --install_prefix is removed, the only way to designate a staging directory is with the Makefile variable (this is also implemented for VMS' descrip.mms et al).

2016-02-03RT3234: disable compressionEmilia Kasper
CRIME protection: disable compression by default, even if OpenSSL is compiled with zlib enabled. Applications can still enable compression by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by using the SSL_CONF library to configure compression. SSL_CONF continues to work as before: SSL_CONF_cmd(ctx, "Options", "Compression") enables compression. SSL_CONF_cmd(ctx, "Options", "-Compression") disables compression (now no-op by default). The command-line switch has changed from -no_comp to -comp. Reviewed-by: Rich Salz <rsalz@openssl.org>

2016-01-22Refresh the thinking of --prefix and --openssldirRichard Levitte
--prefix is now exclusively used for software and manual installation. --openssldir is not exclusively used as a default location for certs, keys and the default openssl.cnf. This change is made to bring clarity, to have the two less intertwined, and to be more compatible with the usual ways of software installation.

Only two macros CRYPTO_MDEBUG and CRYPTO_MDEBUG_ABORT to control this. If CRYPTO_MDEBUG is not set, #ifdef out the whole debug machinery. (Thanks to Jakob Bohm for the suggestion!) Make the "change wrapper functions" be the only paradigm. Wrote documentation! Format the 'set func' functions so their paramlists are legible. Format some multi-line comments. Remove ability to get/set the "memory debug" functions at runtme. Remove MemCheck_* and CRYPTO_malloc_debug_init macros. Add CRYPTO_mem_debug(int flag) function. Add test/memleaktest. Rename CRYPTO_malloc_init to OPENSSL_malloc_init; remove needless calls. Reviewed-by: Richard Levitte <levitte@openssl.org>
2016-01-02Protocol version selection and negotiation rewriteViktor Dukhovni
The protocol selection code is now consolidated in a few consecutive short functions in a single file and is table driven. Protocol-specific constraints that influence negotiation are moved into the flags field of the method structure. The same protocol version constraints are now applied in all code paths. It is now much easier to add new protocol versions without reworking the protocol selection logic. In the presence of "holes" in the list of enabled client protocols we no longer select client protocols below the hole based on a subset of the constraints and then fail shortly after when it is found that these don't meet the remaining constraints (suiteb, FIPS, security level, ...). Ideally, with the new min/max controls users will be less likely to create "holes" in the first place. Reviewed-by: Kurt Roeckx <kurt@openssl.org>
