Denial Of Service (DoS)
openssl is vulnerable to denial of service. A NULL pointer dereference occurs when parsing a malicious renegotiation ClientHello message. This allows an attacker to remotely crash the application...
ALPINE-CVE-2021-3449
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signaturealgorithms extension where it was present in the initial ClientHello, but includes a signaturealgorithmscert extension then a NU...
