CVE-2020-24613 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2020-11735 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2019-14317 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2014-2896 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2019-13628 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2014-2897 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2014-2901 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
wolfssl before 3.2.0 does not properly issue certificates for a server's hostname. | |||||
CVE-2019-18840 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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 | 2023-12-10 | 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-2014-2898 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2014-2904 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
wolfssl before 3.2.0 has a server certificate that is not properly authorized for server authentication. | |||||
CVE-2019-19962 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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 | 2023-12-10 | 4.3 MEDIUM | 5.3 MEDIUM |
In wolfSSL before 4.3.0, wc_ecc_mulmod_ex does not properly resist side-channel attacks. | |||||
CVE-2014-2902 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
wolfssl before 3.2.0 does not properly authorize CA certificate for signing other certificates. | |||||
CVE-2019-19963 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2019-15651 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2019-11873 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2019-6439 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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-2018-16870 | 1 Wolfssl | 1 Wolfssl | 2023-12-10 | 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 | 2023-12-10 | 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. |
