  - CVE-2019-13629: MatrixSSL contains a timing side channel in ECDSA signature generation. This
  allows a local or a remote attacker to measure the duration of hundreds to thousands of signing
  operations, to compute the private key used. The issue occurs because crypto/pubkey/ecc_math.c
  scalar multiplication leaks the bit length of the scalar.

  - CVE-2019-14431: The DTLS server mishandles incoming network messages leading to a heap-based
  buffer overflow of up to 256 bytes and possible Remote Code Execution in parseSSLHandshake in
  sslDecode.c. During processing of a crafted packet, the server mishandles the fragment length
  value provided in the DTLS message.

  - CVE-2019-16747: Memory corruption (free on invalid pointer) while parsing DTLS messages");
