| CVE-2021-38597 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| wolfSSL before 4.8.1 incorrectly skips OCSP verification in certain situations of irrelevant response data that contains the NoCheck extension. | |||||
| CVE-2021-37155 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| wolfSSL 4.6.x through 4.7.x before 4.8.0 does not produce a failure outcome when the serial number in an OCSP request differs from the serial number in the OCSP response. | |||||
| CVE-2021-24116 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 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-2020-36177 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 10.0 HIGH | 9.8 CRITICAL |
| RsaPad_PSS in wolfcrypt/src/rsa.c in wolfSSL before 4.6.0 has an out-of-bounds write for certain relationships between key size and digest size. | |||||
| CVE-2020-24613 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 4.9 MEDIUM | 6.8 MEDIUM |
| wolfSSL before 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 impersonate any TLS 1.3 servers, and read or modify potentially sensitive information between clients using the wolfSSL library and these TLS servers. | |||||
| CVE-2020-24585 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in the DTLS handshake implementation in wolfSSL before 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. | |||||
| CVE-2020-15309 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 6.9 MEDIUM | 7.0 HIGH |
| An issue was discovered in wolfSSL before 4.5.0, when single precision is not employed. Local attackers can conduct a cache-timing attack against public key operations. These attackers may already have obtained sensitive information if the affected system has been used for private key operations (e.g., signing with a private key). | |||||
| CVE-2020-12457 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 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-2020-11735 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak." | |||||
| CVE-2020-11713 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| wolfSSL 4.3.0 has mulmod code in wc_ecc_mulmod_ex in ecc.c that does not properly resist timing side-channel attacks. | |||||
| CVE-2019-6439 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| examples/benchmark/tls_bench.c in a benchmark tool in wolfSSL through 3.15.7 has a heap-based buffer overflow. | |||||
| CVE-2019-19963 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 4.3 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in wolfSSL before 4.3.0 in a non-default configuration where DSA is enabled. DSA signing uses the BEEA algorithm during modular inversion of the nonce, leading to a side-channel attack against the nonce. | |||||
| CVE-2019-19962 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| wolfSSL before 4.3.0 mishandles calls to wc_SignatureGenerateHash, leading to fault injection in RSA cryptography. | |||||
| CVE-2019-19960 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 4.3 MEDIUM | 5.3 MEDIUM |
| In wolfSSL before 4.3.0, wc_ecc_mulmod_ex does not properly resist side-channel attacks. | |||||
| CVE-2019-18840 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| In wolfSSL 4.1.0 through 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 because the domain name location index is mishandled. Because a pointer is overwritten, there is an invalid free. | |||||
| CVE-2019-16748 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| In wolfSSL through 4.1.0, there is a missing sanity check of memory accesses in parsing ASN.1 certificate data while handshaking. Specifically, there is a one-byte heap-based buffer over-read in CheckCertSignature_ex in wolfcrypt/src/asn.c. | |||||
| CVE-2019-15651 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| wolfSSL 4.1.0 has a one-byte heap-based buffer over-read in DecodeCertExtensions in wolfcrypt/src/asn.c because reading the ASN_BOOLEAN byte is mishandled for a crafted DER certificate in GetLength_ex. | |||||
| CVE-2019-14317 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 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-2019-13628 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 1.2 LOW | 4.7 MEDIUM |
| wolfSSL and wolfCrypt 4.0.0 and earlier (when configured without --enable-fpecc, --enable-sp, or --enable-sp-math) contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about the nonces used and potentially mount a lattice attack to recover the private key used. The issue occurs because ecc.c scalar multiplication might leak the bit length. | |||||
| CVE-2019-11873 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 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. | |||||
