| CVE-2019-19963 | 1 Wolfssl | 1 Wolfssl | 2020-01-02 | 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-2019-19960 | 1 Wolfssl | 1 Wolfssl | 2020-01-02 | 4.3 MEDIUM | 5.3 MEDIUM |
| In wolfSSL before 4.3.0, wc_ecc_mulmod_ex does not properly resist side-channel attacks. | |||||
| CVE-2014-2901 | 1 Wolfssl | 1 Wolfssl | 2019-12-04 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 does not properly issue certificates for a server's hostname. | |||||
| CVE-2014-2902 | 1 Wolfssl | 1 Wolfssl | 2019-12-04 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 does not properly authorize CA certificate for signing other certificates. | |||||
| CVE-2014-2904 | 1 Wolfssl | 1 Wolfssl | 2019-12-04 | 5.0 MEDIUM | 7.5 HIGH |
| wolfssl before 3.2.0 has a server certificate that is not properly authorized for server authentication. | |||||
| CVE-2019-18840 | 1 Wolfssl | 1 Wolfssl | 2019-11-12 | 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-2019-13628 | 1 Wolfssl | 1 Wolfssl | 2019-10-10 | 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-2018-16870 | 1 Wolfssl | 1 Wolfssl | 2019-10-09 | 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-2017-13099 | 3 Arubanetworks, Siemens, Wolfssl | 4 Instant, Scalance W1750d, Scalance W1750d Firmware and 1 more | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| wolfSSL prior to version 3.12.2 provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable wolfSSL application. This vulnerability is referred to as "ROBOT." | |||||
| CVE-2017-8855 | 1 Wolfssl | 1 Wolfssl | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| wolfSSL before 3.11.0 does not prevent wc_DhAgree from accepting a malformed DH key. | |||||
| CVE-2019-16748 | 1 Wolfssl | 1 Wolfssl | 2019-09-24 | 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 | 2019-09-03 | 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-2017-6076 | 1 Wolfssl | 1 Wolfssl | 2019-03-13 | 2.1 LOW | 5.5 MEDIUM |
| In versions of wolfSSL before 3.10.2 the function fp_mul_comba makes it easier to extract RSA key information for a malicious user who has access to view cache on a machine. | |||||
| CVE-2018-12436 | 1 Wolfssl | 1 Wolfssl | 2018-08-06 | 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-2014-2903 | 1 Wolfssl | 1 Wolfssl | 2017-10-17 | 4.3 MEDIUM | 5.9 MEDIUM |
| CyaSSL does not check the key usage extension in leaf certificates, which allows remote attackers to spoof servers via a crafted server certificate not authorized for use in an SSL/TLS handshake. | |||||
| CVE-2017-8854 | 1 Wolfssl | 1 Wolfssl | 2017-05-17 | 6.8 MEDIUM | 7.8 HIGH |
| wolfSSL before 3.10.2 has an out-of-bounds memory access with loading crafted DH parameters, aka a buffer overflow triggered by a malformed temporary DH file. | |||||
| CVE-2016-7439 | 1 Wolfssl | 1 Wolfssl | 2016-12-24 | 2.1 LOW | 5.5 MEDIUM |
| The C software implementation of RSA in wolfSSL (formerly CyaSSL) before 3.9.10 makes it easier for local users to discover RSA keys by leveraging cache-bank hit differences. | |||||
| CVE-2016-7438 | 1 Wolfssl | 1 Wolfssl | 2016-12-24 | 2.1 LOW | 5.5 MEDIUM |
| The C software implementation of ECC in wolfSSL (formerly CyaSSL) before 3.9.10 makes it easier for local users to discover RSA keys by leveraging cache-bank hit differences. | |||||
| CVE-2015-6925 | 1 Wolfssl | 1 Wolfssl | 2016-01-25 | 5.0 MEDIUM | 7.5 HIGH |
| wolfSSL (formerly CyaSSL) before 3.6.8 allows remote attackers to cause a denial of service (resource consumption or traffic amplification) via a crafted DTLS cookie in a ClientHello message. | |||||
