| CVE-2022-39173 | 1 Wolfssl | 1 Wolfssl | 2023-08-08 | N/A | 7.5 HIGH |
| In wolfSSL before 5.5.1, malicious clients can cause a buffer overflow during a TLS 1.3 handshake. This occurs when an attacker supposedly resumes a previous TLS session. During the resumption Client Hello a Hello Retry Request must be triggered. Both Client Hellos are required to contain a list of duplicate cipher suites to trigger the buffer overflow. In total, two Client Hellos have to be sent: one in the resumed session, and a second one as a response to a Hello Retry Request message. | |||||
| CVE-2022-25640 | 1 Wolfssl | 1 Wolfssl | 2023-08-08 | 5.0 MEDIUM | 7.5 HIGH |
| In wolfSSL before 5.2.0, a TLS 1.3 server cannot properly enforce a requirement for mutual authentication. A client can simply omit the certificate_verify message from the handshake, and never present a certificate. | |||||
| CVE-2023-3724 | 1 Wolfssl | 1 Wolfssl | 2023-07-28 | N/A | 8.8 HIGH |
| If a TLS 1.3 client gets neither a PSK (pre shared key) extension nor a KSE (key share extension) when connecting to a malicious server, a default predictable buffer gets used for the IKM (Input Keying Material) value when generating the session master secret. Using a potentially known IKM value when generating the session master secret key compromises the key generated, allowing an eavesdropper to reconstruct it and potentially allowing access to or meddling with message contents in the session. This issue does not affect client validation of connected servers, nor expose private key information, but could result in an insecure TLS 1.3 session when not controlling both sides of the connection. wolfSSL recommends that TLS 1.3 client side users update the version of wolfSSL used. | |||||
| CVE-2022-23408 | 1 Wolfssl | 1 Wolfssl | 2022-01-27 | 6.4 MEDIUM | 9.1 CRITICAL |
| wolfSSL 5.x before 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. | |||||

| CVE-2021-24116 | 1 Wolfssl | 1 Wolfssl | 2021-07-22 | 4.0 MEDIUM | 4.9 MEDIUM |
| In wolfSSL through 4.6.0, a side-channel vulnerability in base64 PEM file decoding allows system-level (administrator) attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single stepped, especially Intel SGX. | |||||
| CVE-2020-12457 | 1 Wolfssl | 1 Wolfssl | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in wolfSSL before 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., a denial of service. | |||||
| CVE-2019-11873 | 1 Wolfssl | 1 Wolfssl | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| wolfSSL 4.0.0 has a Buffer Overflow in DoPreSharedKeys in tls13.c when a current identity size is greater than a client identity size. An attacker sends a crafted hello client packet over the network to a TLSv1.3 wolfSSL server. The length fields of the packet: record length, client hello length, total extensions length, PSK extension length, total identity length, and identity length contain their maximum value which is 2^16. The identity data field of the PSK extension of the packet contains the attack data, to be stored in the undefined memory (RAM) of the server. The size of the data is about 65 kB. Possibly the attacker can perform a remote code execution attack. | |||||
| CVE-2019-14317 | 1 Wolfssl | 1 Wolfssl | 2021-07-21 | 4.3 MEDIUM | 5.3 MEDIUM |
| wolfSSL and wolfCrypt 4.1.0 and earlier (formerly known as CyaSSL) generate biased DSA nonces. This allows a remote attacker to compute the long term private key from several hundred DSA signatures via a lattice attack. The issue occurs because dsa.c fixes two bits of the generated nonces. | |||||
| CVE-2019-19962 | 1 Wolfssl | 1 Wolfssl | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
