2015-01-30Rework vis.3 so it has standard sections.Doug Hogan
Moved the return values from the description to a proper return values section. Broke up the description into function description followed by a subsection for the range and encoding. Replaced srclen with strlen(src) when srclen isn't an argument. Moved the common flag argument to its own paragraph. input schwarze@, input + ok jmc@

2015-01-26Add AEAD as a "MAC alias" so that it is possible to identify/select ciphersJoel Sing
that use AEAD instead of a MAC. This allows for TLSv1.2 AEAD ciphers (effectively the only ciphers that are still considered to be secure) to be selected using TLSv1.2+AEAD as a cipher string. ok bcook@ doug@ miod@

2015-01-23Ensure that a ServerKeyExchange message is received if the selected cipherJoel Sing
suite uses ephemeral keys. This avoids an issue where an ECHDE cipher suite can effectively be downgraded to ECDH, if the server omits the ServerKeyExchange message and has provided a certificate with an ECC public key. Issue reported to OpenSSL by Karthikeyan Bhargavan. Based on OpenSSL. Fixes CVE-2014-3572. ok beck@

2015-01-22Add MLINK for tls_config_set_ca_mem()Reyk Floeter
2015-01-22Allow to to load the CA chain directly from memory instead ofReyk Floeter
specifying a file. This enables CA verification in privsep'ed processes that are running chroot'ed without direct access to the certificate files. With feedback, tests, and OK from bluhm@
2015-01-22Support CA verification in chroot'ed processes without direct fileReyk Floeter
access to the certificates. SSL_CTX_load_verify_mem() is a frontend to the new X509_STORE_load_mem() function that allows to load the CA chain from a memory buffer that is holding the PEM-encoded files. This function allows to handle the verification in privsep'ed code. Adopted for LibreSSL based on older code from relayd (by pyr@ and myself) With feedback and OK bluhm@
2015-01-22Add X509_STORE_load_mem() to load certificates from a memory bufferReyk Floeter
instead of disk. OpenSSL didn't provide a built-in API from loading certificates in a chroot'ed process that doesn't have direct access to the files. X509_STORE_load_mem() provides a new backend that will be used by libssl and libtls to implement such privsep-friendly functionality. Adopted for LibreSSL based on older code from relayd (by pyr@ and myself) With feedback and OK bluhm@

2015-01-21Fix DTLS memory leak (CVE-2015-0206).Doug Hogan
There were four bugs fixed by this patch: * dtls1_buffer_record() now frees rdata->rbuf.buf on error. Since s->s3->rbuf was memset, rdata->rbuf is the only pointer left which points to the old rbuf. On error, rdata is freed so there will not be any way of freeing this memory unless we do it here. * Changed the return code of dtls1_buffer_record() to differentiate between queue full (0) and error (-1). See below as this differs from upstream. * Handle errors if calls to dtls1_buffer_record() fail with -1. Previously, it did not check the return value. * Changed the way receipts are recorded. Previously, it was recorded when processed successfully (whether buffered or not) in dtls1_process_record(). Now, it records when it is handled in dtls1_get_record(): either when it is entered into the queue to buffer for the next epoch or when it is processed directly. Processing buffered records does not add a receipt because it needed one in order to get into the queue. The above bugs combined contributed to an eventual DoS through memory exhaustion. The memory leak came from dtls1_buffer_record()'s error handling. The error handling can be triggered by a duplicate record or malloc failure. It was possible to add duplicate records because they were not being dropped. The faulty receipts logic did not detect replays when dealing with records for the next epoch. Additionally, dtls1_buffer_record()'s return value was not checked so an attacker could send repeated replay records for the next epoch. Reported to OpenSSL by Chris Mueller. Patch based on OpenSSL commit 103b171d8fc282ef435f8de9afbf7782e312961f and BoringSSL commit 44e2709cd65fbd2172b9516c79e56f1875f60300. Our patch matches BoringSSL's commit. OpenSSL returns 0 when the queue is full or when malloc() or pitem_new() fails. They return -1 on error including !ssl3_setup_buffers() which is another failure to allocate memory. BoringSSL and LibreSSL changed the return code for dtls1_buffer_record() to be 1 on success, 0 when the queue is full and -1 on error. input + ok bcook@, jsing@
