CVE-2023-6135

The Network Security Services NSS package contains a vulnerability that exposes a side-channel information leak. This weakness enables a local attacker to capture several thousand usages of a signature, allowing them to utilize this information to recover portions of an ECDSA private key...

Signature Malleability in CultureIndex::_verifyVoteSignature function

Lines of code Vulnerability details Impact The elliptic curve used in Ethereum for signatures is symmetrical, hence for every v,r,s there exists another v,r,s that returns the same valid result. Therefore two valid signatures exist which allows attackers to compute a valid signature without knowi...

PT-2023-9405

Name of the Vulnerable Software and Affected Versions WolfSSL affected versions not specified Description The issue is related to the generation of the ECDSA nonce k, where a random number r is selected and then reduced modulo n, the order of the elliptic curve. The division used during the...

Rockwell Automation Stratix ECDSA NONCE Side-Channel Recovery Attack (CVE-2014-0076)

Multiple Cisco products incorporate a version of the OpenSSL package affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to execute arbitrary code, create a denial of service DoS condition, or perform a man-in-the-middle attack. This plugin only works with...

GHSA-RJJM-X32P-M3F7 gnark's range checker gadget allows wider inputs up to word alignment
