4.3
CVSSv2
CVE-2014-2903
CyaSSL does not check the key usage extension in leaf certificates, which allows remote malicious users to spoof servers via a crafted server certificate not authorized for use in an SSL/TLS handshake.

6.4
CVSSv2
CVE-2022-23408
wolfSSL 5.x prior to 5.1.1 uses non-random IV values in certain situations. This affects connections (without AEAD) using AES-CBC or DES3 with TLS 1.1 or 1.2 or DTLS 1.1 or 1.2. This occurs because of misplaced memory initialization in BuildMessage in internal.c.

CVSSv2
CVE-2019-14317
wolfSSL and wolfCrypt 4.1.0 and previous versions (formerly known as CyaSSL) generate biased DSA nonces. This allows a remote malicious user to compute the long term private key from several hundred DSA signatures via a lattice attack. The issue occurs because dsa.c fixes two bit...

CVE-2020-12457
An issue exists in wolfSSL prior to 4.5.0. It mishandles the change_cipher_spec (CCS) message processing logic for TLS 1.3. If an attacker sends ChangeCipherSpec messages in a crafted way involving more than one in a row, the server becomes stuck in the ProcessReply() loop, i.e.,...

CVSSv2
CVE-2020-24585
An issue exists in the DTLS handshake implementation in wolfSSL prior to 4.5.0. Clear DTLS application_data messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application.

CVSSv2
CVE-2020-24613
wolfSSL prior to 4.5.0 mishandles TLS 1.3 server data in the WAIT_CERT_CR state, within SanityCheckTls13MsgReceived() in tls13.c. This is an incorrect implementation of the TLS 1.3 client state machine. This allows attackers in a privileged network position to completely imperson...

CVE-2019-18840
In wolfSSL 4.1.0 up to and including 4.2.0c, there are missing sanity checks of memory accesses in parsing ASN.1 certificate data while handshaking. Specifically, there is a one-byte heap-based buffer overflow inside the DecodedCert structure in GetName in wolfcrypt/src/asn.c bec...
