 = mbed TLS 2.x branch
 
+Security
+   * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt
+     required by PKCS1 v2.2
+   * Fix potential integer overflow to buffer overflow in
+     mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt
+     (not triggerable remotely in (D)TLS).
+   * Fix a potential integer underflow to buffer overread in 
+     mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in
+     SSL/TLS.
+
 Bugfix
    * 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
