* RSA blinding on CRT operations to counter timing attacks
(found by Cyril Arnaud and Pierre-Alain Fouque)
= Version 1.2.14 released 2015-05-??
Security
* Fix potential invalid memory read in the server, that allows a client to
crash it remotely (found by Caj Larsson).
* Fix potential invalid memory read in certificate parsing, that allows a
client to crash the server remotely if client authentication is enabled
(found using Codenomicon Defensics).
* Add countermeasure against "Lucky 13 strikes back" cache-based attack,

Bugfix
* Fix bug in Via Padlock support (found by Nikos Mavrogiannopoulos).
* Fix hardclock() (only used in the benchmarking program) with some
versions of mingw64 (found by kxjhlele).
* Fix warnings from mingw64 in timing.c (found by kxjklele).
* Fix potential unintended sign extension in asn1_get_len() on 64-bit
platforms (found with Coverity Scan).
= Version 1.2.13 released 2015-02-16
Note: Although PolarSSL has been renamed to mbed TLS, no changes reflecting
this will be made in the 1.2 branch at this point.
Security
* Fix remotely-triggerable uninitialised pointer dereference caused by
crafted X.509 certificate (TLS server is not affected if it doesn't ask
for a client certificate) (found using Codenomicon Defensics).
* Fix remotely-triggerable memory leak caused by crafted X.509 certificates
(TLS server is not affected if it doesn't ask for a client certificate)
(found using Codenomicon Defensics).
* Fix potential stack overflow while parsing crafted X.509 certificates
(TLS server is not affected if it doesn't ask for a client certificate)
found using Codenomicon Defensics).
* Fix buffer overread of size 1 when parsing crafted X.509 certificates
(TLS server is not affected if it doesn't ask for a client certificate).
Bugfix
* Fix potential undefined behaviour in Camellia.
* Fix memory leaks in PKCS#5 and PKCS#12.
* Stack buffer overflow if ctr_drbg_update() is called with too large
add_len (found by Jean-Philippe Aumasson) (not triggerable remotely).
* Fix bug in MPI/bignum on s390/s390x (reported by Dan Horák) (introduced
in 1.2.12).
* Fix unchecked return code in x509_crt_parse_path() on Windows (found by
Peter Vaskovic).
* Fix assembly selection for MIPS64 (thanks to James Cowgill).
* ssl_get_verify_result() now works even if the handshake was aborted due
to a failed verification (found by Fredrik Axelsson).
* Skip writing and parsing signature_algorithm extension if none of the
key exchanges enabled needs certificates. This fixes a possible interop
issue with some servers when a zero-length extension was sent. (Reported
by Peter Dettman.)
* On a 0-length input, base64_encode() did not correctly set output length
(found by Hendrik van den Boogaard).
Changes
* Blind RSA private operations even when POLARSSL_RSA_NO_CRT is defined.
* Forbid repeated extensions in X.509 certificates.
* Add compile-time option POLARSSL_X509_MAX_INTERMEDIATE_CA to limit the
length of an X.509 verification chain (default = 8).
