CVE-2022-25638
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 sigalgo field differs between the certificateverify message and the certificate message...
CVE-2022-42961
An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via ...
CVE-2022-34293
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-2022-39173
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 ...
CVE-2021-38597
wolfSSL before 4.8.1 incorrectly skips OCSP verification in certain situations of irrelevant response data that contains the NoCheck extension...
CVE-2021-45939
wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClientDecodePacket called from MqttClientWaitType and MqttClientSubscribe...
CVE-2021-45938
wolfSSL wolfMQTT 1.9 has a heap-based buffer overflow in MqttClientDecodePacket called from MqttClientWaitType and MqttClientUnsubscribe...
CVE-2021-24116
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,...
CVE-2021-3336
DoTls13CertificateVerify in tls13.c in wolfSSL before 4.7.0 does not cease processing for certain anomalous peer behavior sending an ED22519, ED448, ECC, or RSA signature without the corresponding certificate. The client side is affected because man-in-the-middle attackers can impersonate TLS 1.3...
CVE-2021-37155
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-2020-12457
An issue was discovered in wolfSSL before 4.5.0. It mishandles the changecipherspec 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...
CVE-2020-36177
RsaPadPSS 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-2020-15309
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...
CVE-2020-11713
wolfSSL 4.3.0 has mulmod code in wceccmulmodex in ecc.c that does not properly resist timing side-channel attacks...
CVE-2019-14317
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
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 th...
CVE-2019-19963
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-2019-19960
In wolfSSL before 4.3.0, wceccmulmodex does not properly resist side-channel attacks...
