- Update to version 1.3.17 (boo#988956):
+ Fix missing padding length check in
mbedtls_rsa_rsaes_pkcs1_v15_decrypt required by PKCS1 v2.2
+ Fix a potential integer underflow to buffer overread in
mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable
remotely in SSL/TLS.
+ Fix potential integer overflow to buffer overflow in
+ Fix bug in mbedtls_mpi_add_mpi() that caused wrong results
when the three arguments where the same (in-place doubling).
Found and fixed by Janos Follath. #309
+ Fix issue in Makefile that prevented building using armar.
+ Fix issue that caused a hang up when generating RSA keys of
+ Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made
null pointer dereference possible.
+ Fix issue that caused a crash if invalid curves were passed
to mbedtls_ssl_conf_curves. #373
+ On ARM platforms, when compiling with -O0 with GCC, Clang or
armcc5, don't use the optimized assembly for bignum
multiplication. This removes the need to pass
- fomit-frame-pointer to avoid a build error with -O0.
+ Disabled SSLv3 in the default configuration.
+ Fix non-compliance server extension handling. Extensions for
SSLv3 are now ignored, as required by RFC6101.

- Update to 1.3.16
* Fixes a potential double free when
mbedtls_asn1_store_named_data() fails to allocate memory. This
was only used for certificate generation and was not
triggerable remotely in SSL/TLS. boo#961290
* Disables by default MD5 handshake signatures in TLS 1.2 to
prevent the SLOTH (CVE-2015-7575) attack on TLS 1.2 server
authentication (other attacks from the SLOTH paper do not apply
to any version of mbed TLS or PolarSSL). boo#961284
* Fixes an over-restrictive length limit in GCM.
* Fixes a bug in certificate validation that caused valid chains
to be rejected when the first intermediate certificate has a
pathLenConstraint equal to zero.
* Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign()
* Added config.h option POLARSSL_SSL_ENABLE_MD5_SIGNATURES to

Cannot be triggered remotely unless you create X.509 certificates based
on untrusted input or write keys of untrusted origin. Found by Guido

certificates. Found by Nicholas Wilson, fix and tests provided by
Janos Follath. #280 and #319

resulting in some valid X.509 being incorrectly rejected. Found and fix
provided by Janos Follath. #319

begin properly ignored. Found by mancha and Kasom Koht-arsa, #308

Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
of TLS, but might be in other uses. On 32 bit machines, requires reading a
string of close to or larger than 1GB to exploit; on 64 bit machines, would
require reading a string of close to or larger than 2^62 bytes.
