| 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. | |||||
| CVE-2018-16870 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| It was found that wolfssl before 3.15.7 is vulnerable to a new variant of the Bleichenbacher attack to perform downgrade attacks against TLS. This may lead to leakage of sensible data. | |||||
| CVE-2018-12436 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 1.9 LOW | 4.7 MEDIUM |
| wolfcrypt/src/ecc.c in wolfSSL before 3.15.1.patch allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | |||||
| CVE-2014-2904 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 has a server certificate that is not properly authorized for server authentication. | |||||
| CVE-2014-2902 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 does not properly authorize CA certificate for signing other certificates. | |||||
| CVE-2014-2901 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 does not properly issue certificates for a server's hostname. | |||||
| CVE-2014-2898 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| wolfSSL CyaSSL before 2.9.4 allows remote attackers to have unspecified impact via multiple calls to the CyaSSL_read function which triggers an out-of-bounds read when an error occurs, related to not checking the return code and MAC verification failure. | |||||
| CVE-2014-2897 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| The SSL 3 HMAC functionality in wolfSSL CyaSSL 2.5.0 before 2.9.4 does not check the padding length when verification fails, which allows remote attackers to have unspecified impact via a crafted HMAC, which triggers an out-of-bounds read. | |||||
| CVE-2014-2896 | 1 Wolfssl | 1 Wolfssl | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| The DoAlert function in the (1) TLS and (2) DTLS implementations in wolfSSL CyaSSL before 2.9.4 allows remote attackers to have unspecified impact and vectors, which trigger memory corruption or an out-of-bounds read. | |||||
| 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 | 6.7 MEDIUM |
| 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 | 5.9 MEDIUM |
| 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 | 4.1 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.
