wolfSSL blog reports: In release 5.4.0 there were 3 vulnerabilities listed as fixed in wolfSSL. Two relatively new reports, one dealing with a DTLS 1.0/1.2 denial of service attack and the other a ciphertext attack on ECC/DH operations. The last vulnerability listed was a public disclosure of a previous attack on AMD devices fixed since wolfSSL version 5.1.0.
