| CVE-2023-6935 | 1 Wolfssl | 1 Wolfssl | 2024-11-07 | N/A | 5.9 MEDIUM |
| wolfSSL SP Math All RSA implementation is vulnerable to the Marvin Attack, new variation of a timing Bleichenbacher style attack, when built with the following options to configure: --enable-all CFLAGS="-DWOLFSSL_STATIC_RSA" The define “WOLFSSL_STATIC_RSA” enables static RSA cipher suites, which is not recommended, and has been disabled by default since wolfSSL 3.6.6. Therefore the default build since 3.6.6, even with "--enable-all", is not vulnerable to the Marvin Attack. The vulnerability is specific to static RSA cipher suites, and expected to be padding-independent. The vulnerability allows an attacker to decrypt ciphertexts and forge signatures after probing with a large number of test observations. However the server’s private key is not exposed. | |||||
| CVE-2024-5991 | 1 Wolfssl | 1 Wolfssl | 2024-09-06 | N/A | 7.5 HIGH |
| In function MatchDomainName(), input param str is treated as a NULL terminated string despite being user provided and unchecked. Specifically, the function X509_check_host() takes in a pointer and length to check against, with no requirements that it be NULL terminated. If a caller was attempting to do a name check on a non-NULL terminated buffer, the code would read beyond the bounds of the input array until it found a NULL terminator.This issue affects wolfSSL: through 5.7.0. | |||||
| CVE-2024-2881 | 3 Linux, Microsoft, Wolfssl | 3 Linux Kernel, Windows, Wolfssl | 2024-09-04 | N/A | 8.8 HIGH |
| Fault Injection vulnerability in wc_ed25519_sign_msg function in wolfssl/wolfcrypt/src/ed25519.c in WolfSSL wolfssl5.6.6 on Linux/Windows allows remote attacker co-resides in the same system with a victim process to disclose information and escalate privileges via Rowhammer fault injection to the ed25519_key structure. | |||||
| CVE-2024-1545 | 3 Linux, Microsoft, Wolfssl | 3 Linux Kernel, Windows, Wolfssl | 2024-09-04 | N/A | 8.8 HIGH |
| Fault Injection vulnerability in RsaPrivateDecryption function in wolfssl/wolfcrypt/src/rsa.c in WolfSSL wolfssl5.6.6 on Linux/Windows allows remote attacker co-resides in the same system with a victim process to disclose information and escalate privileges via Rowhammer fault injection to the RsaKey structure. | |||||
| CVE-2024-1543 | 1 Wolfssl | 1 Wolfssl | 2024-09-04 | N/A | 5.5 MEDIUM |
| The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the cache-line-level protection. For details on the attack refer to: https://doi.org/10.46586/tches.v2024.i1.457-500 | |||||
| CVE-2023-3724 | 1 Wolfssl | 1 Wolfssl | 2024-02-05 | 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-2021-44718 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | N/A | 5.9 MEDIUM |
| wolfSSL through 5.0.0 allows an attacker to cause a denial of service and infinite loop in the client component by sending crafted traffic from a Machine-in-the-Middle (MITM) position. The root cause is that the client module accepts TLS messages that normally are only sent to TLS servers. | |||||
| CVE-2022-42905 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | N/A | 9.1 CRITICAL |
| In wolfSSL before 5.5.2, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. (WOLFSSL_CALLBACKS is only intended for debugging.) | |||||
| CVE-2022-34293 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2022-38153 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | N/A | 5.9 MEDIUM |
| An issue was discovered in wolfSSL before 5.5.0 (when --enable-session-ticket is used); however, only version 5.3.0 is exploitable. Man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket (more than 256 bytes) into a NewSessionTicket message in a TLS 1.2 handshake, and the client has a non-empty session cache, the session cache frees a pointer that points to unallocated memory, causing the client to crash with a "free(): invalid pointer" message. NOTE: It is likely that this is also exploitable during TLS 1.3 handshakes between a client and a malicious server. With TLS 1.3, it is not possible to exploit this as a man-in-the-middle. | |||||
| CVE-2022-42961 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | N/A | 5.3 MEDIUM |
| 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 an advanced technique for ECDSA key recovery. (In 5.5.0 and later, WOLFSSL_CHECK_SIG_FAULTS can be used to address the vulnerability.) | |||||
| CVE-2022-38152 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | N/A | 7.5 HIGH |
| An issue was discovered in wolfSSL before 5.5.0. When a TLS 1.3 client connects to a wolfSSL server and SSL_clear is called on its session, the server crashes with a segmentation fault. This occurs in the second session, which is created through TLS session resumption and reuses the initial struct WOLFSSL. If the server reuses the previous session structure (struct WOLFSSL) by calling wolfSSL_clear(WOLFSSL* ssl) on it, the next received Client Hello (that resumes the previous session) crashes the server. Note that this bug is only triggered when resuming sessions using TLS session resumption. Only servers that use wolfSSL_clear instead of the recommended SSL_free; SSL_new sequence are affected. Furthermore, wolfSSL_clear is part of wolfSSL's compatibility layer and is not enabled by default. It is not part of wolfSSL's native API. | |||||
| CVE-2022-39173 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2022-25638 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2022-25640 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2022-23408 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2021-38597 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2021-24116 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2021-37155 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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-2020-36177 | 1 Wolfssl | 1 Wolfssl | 2024-02-04 | 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. | |||||
