CVE-2019-19963

wolfSSL before 4.3.0 in a non-default configuration with DSA enabled is vulnerable. DSA signing uses the BEEA algorithm during nonce modular inversion, enabling a side-channel attack on the nonce. Affected: wolfSSL prior to 4.3.0 (non-default DSA). Remediation: upgrade to 4.3.0-stable (or apply v...

Unspecified vulnerability in wolfSSL (CNVD-2020-01644)

wolfSSL formerly known as CyaSSL is the United States wolfSSL company for embedded systems developers to use a small, portable embedded SSL programming library. A security vulnerability exists in the 'wceccmulmodex' function in wolfSSL versions prior to 4.3.0, which can be exploited by an attacke...

PT-2019-16022

Name of the Vulnerable Software and Affected Versions wolfSSL versions prior to 4.3.0 Description The issue is related to the wc ecc mulmod ex function, which does not properly resist side-channel attacks. Recommendations For versions prior to 4.3.0, update to version 4.3.0 or later to resolve th...

CVE-2019-14317

Summary of the vulnerability (CVE-2019-14317) : In wolfSSL/wolfCrypt up to version 4.1.0, DSA nonces are biased because dsa.c fixes two bits of the nonces. This bias makes it possible for a remote attacker to recover the long-term DSA private key after observing several hundred signatures, via a ...
