CVE-2019-14431
In MatrixSSL 3.8.3 Open through 4.2.1 Open, 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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
