| CVE-2015-7744 | 3 Mariadb, Opensuse, Wolfssl | 4 Mariadb, Leap, Opensuse and 1 more | 2022-08-29 | 2.6 LOW | 5.9 MEDIUM |
| wolfSSL (formerly CyaSSL) before 3.6.8 does not properly handle faults associated with the Chinese Remainder Theorem (CRT) process when allowing ephemeral key exchange without low memory optimizations on a server, which makes it easier for remote attackers to obtain private RSA keys by capturing TLS handshakes, aka a Lenstra attack. | |||||
| CVE-2022-34293 | 1 Wolfssl | 1 Wolfssl | 2022-08-12 | N/A | 7.5 HIGH |
| wolfSSL before 5.4.0 allows remote attackers to cause a denial of service via DTLS because a check for return-routability can be skipped. | |||||
| CVE-2019-11873 | 1 Wolfssl | 1 Wolfssl | 2022-04-22 | 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-2022-25638 | 1 Wolfssl | 1 Wolfssl | 2022-03-04 | 4.3 MEDIUM | 6.5 MEDIUM |
| In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sig_algo field differs between the certificate_verify message and the certificate message. | |||||
| 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-2021-45939 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClient_DecodePacket (called from MqttClient_WaitType and MqttClient_Subscribe). | |||||
| CVE-2021-45938 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClient_DecodePacket (called from MqttClient_WaitType and MqttClient_Unsubscribe). | |||||
| CVE-2021-45937 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClient_DecodePacket (called from MqttClient_WaitType and MqttClient_Connect). | |||||
| CVE-2021-45936 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttDecode_Disconnect (called from MqttClient_DecodePacket and MqttClient_WaitType). | |||||
| CVE-2021-45934 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClient_DecodePacket (called from MqttClient_HandlePacket and MqttClient_WaitType). | |||||
| CVE-2021-45933 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow (8 bytes) in MqttDecode_Publish (called from MqttClient_DecodePacket and MqttClient_HandlePacket). | |||||
| CVE-2021-45932 | 1 Wolfssl | 1 Wolfmqtt | 2022-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow (4 bytes) in MqttDecode_Publish (called from MqttClient_DecodePacket and MqttClient_HandlePacket). | |||||
| CVE-2020-11713 | 1 Wolfssl | 1 Wolfssl | 2022-01-01 | 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-2021-38597 | 1 Wolfssl | 1 Wolfssl | 2021-08-23 | 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 | 2021-07-29 | 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 | 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-2019-14317 | 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 |
| wolfSSL before 4.3.0 mishandles calls to wc_SignatureGenerateHash, leading to fault injection in RSA cryptography. | |||||
| CVE-2020-11735 | 1 Wolfssl | 1 Wolfssl | 2021-07-21 | 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." | |||||
