  The following vulnerability was fixed:

  CVE-2017-2784: A remote user could have used a specially crafted
  certificate to cause mbedtls to free a buffer allocated on the stack when
  verifying the validity
  of public key with a secp224k1 curve, which could have
  allowed remote code execution on some platforms (boo#1029017)

  The following non-security changes are included:

  - Add checks to prevent signature forgeries for very large messages while
  using RSA through the PK module in 64-bit systems.

  - Fixed potential livelock during the parsing of a CRL in PEM format");
