| | | | | | | | | an additional 28 bytes of .rodata (or .data) is provided to the network. In most cases this is a non-issue since the memory content is already public. Issue found and reported by Felix Groebert of the Google Security Team. ok bcook@ beck@

* Reduce usage of predefined strings in manpages.bentley2015-02-281-7/+7
| | | | | | | | | | | Predefined strings are not very portable across troff implementations, and they make the source much harder to read. Usually the intended character can be written directly. No output changes, except for two instances where the incorrect escape was used in the first place. tweaks + ok schwarze@

* Fix CVE-2014-3570: properly calculate the square of a BIGNUM value.bcook2015-02-257-1331/+672
| | | | | | | | | | | See https://www.openssl.org/news/secadv_20150108.txt for a more detailed discussion. Original OpenSSL patch here: https://github.com/openssl/openssl/commit/a7a44ba55cb4f884c6bc9ceac90072dea38e66d0 The regression test is modified a little for KNF. ok miod@

| | | | Remove unneeded dangling else, compound statements on a single line.
* Avoid NULL pointer deref in hashinfo_free() when calling from error paths.doug2015-02-251-2/+3
| | | | | | Also, nuke debugging printfs per jsing and bcook. ok bcook@, jsing@

| | | | | | | | | | certificates without requiring a CertificateVerify message. From OpenSSL commit: https://github.com/openssl/openssl/commit/1421e0c584ae9120ca1b88098f13d6d2e90b83a3 Thanks to Karthikeyan Bhargavan for reporting this. ok miod@

* Set errno to EINVAL, instead of letting ERANGE escape out.tedu2015-02-241-2/+4
| | | | | | Printing strerror() in that case will say result too large, even if rounds is actually too small. invalid is less specific, but less incorrect. ok millert

| | | | | | | | using *at functions is equivalent to chdir()ing, which eases portability. Tested with mixes of absolute and relative paths. Eliminate a FILE leak too. prodded by jsing@
* Bump libcrypto and libssl majors, due to various recent churn.jsing2015-02-224-4/+4
| | | | Discussed with/requested by deraadt@ at the conclusion of s2k15.
* Reluctantly add server-side support for TLS_FALLBACK_SCSV.jsing2015-02-2215-25/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows for clients that willingly choose to perform a downgrade and attempt to establish a second connection at a lower protocol after the previous attempt unexpectedly failed, to be notified and have the second connection aborted, if the server does in fact support a higher protocol. TLS has perfectly good version negotiation and client-side fallback is dangerous. Despite this, in order to maintain maximum compatability with broken web servers, most mainstream browsers implement this. Furthermore, TLS_FALLBACK_SCSV only works if both the client and server support it and there is effectively no way to tell if this is the case, unless you control both ends. Unfortunately, various auditors and vulnerability scanners (including certain online assessment websites) consider the presence of a not yet standardised feature to be important for security, even if the clients do not perform client-side downgrade or the server only supports current TLS protocols. Diff is loosely based on OpenSSL with some inspiration from BoringSSL. Discussed with beck@ and miod@. ok bcook@

* In the interests of being secure by default, make the default TLS ciphersjsing2015-02-222-2/+17
| | | | | | | be those that are TLSv1.2 with AEAD and PFS. Provide a "compat" mode that allows the previous default ciphers to be selected. Discussed with tedu@ during s2k15.

* If BN_rand() or BN_pseudo_rand() are called with a NULL rnd argument,jsing2015-02-192-6/+16
| | | | | | | | | BN_bin2bn() will helpfully allocate a BN which is then leaked. Avoid this by explicitly checking for NULL at the start of the bnrand() function. Fixes Coverity ID 78831. ok miod@

* Avoid calling BN_CTX_end() on a context that wasn't started.doug2015-02-152-8/+8
| | | | | | | | | | | In dsa_builtin_paramgen(), if BN_MONT_CTX_new() fails, the BN_CTX_new() call above it will have allocated a ctx without calling BN_CTX_start() on it. The error handling calls BN_CTX_end() when ctx is allocated. Move the BN_MONT_CTX_new() call up so it will fail first without splitting up the BN_CTX_new() and BN_CTX_start(). tweak + ok miod@, ok bcook@
* Use "In" to mark up include files, instead of wrongly wrapping with Aq.bentley2015-02-151-3/+3
