The vulnerability of the WOLFSSL_CHECKSIG_FAULTS configuration in the SSL/TLS WolfSSL library allows a perpetrator to gain unauthorized access to protected information. [source-iocs-preserved const=WOLFSSL_CHECK_SIG_FAULTS]

The vulnerability of the WOLFSSLCHECKSIGFAULTS configuration in the SSL/TLS library WolfSSL is related to improper verification of the ECDSA cryptographic signature. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information by performing a Rowhammer...

gnark's range checker gadget allows wider inputs up to word alignment

Impact gnark provides a gadget in the standard library to allow optimized checking of the bitwidth of the inputs. The gadget works by constructing a fixed lookup table containing all valid entries, partitioning the input and checking that all parts are inside the lookup table. The range checker...

USN-5546-1 openjdk-8, openjdk-lts, openjdk-17, openjdk-18 vulnerabilities

Neil Madden discovered that OpenJDK did not properly verify ECDSA signatures. A remote attacker could possibly use this issue to insert, edit or obtain sensitive information. This issue only affected OpenJDK 17 and OpenJDK 18. CVE-2022-21449 It was discovered that OpenJDK incorrectly limited memo...

CVE-2021-43393

STMicroelectronics STSAFE-J 1.1.4, J-SAFE3 1.2.5, and J-SIGN sometimes allow attackers to abuse signature verification. This is associated with the ECDSA signature algorithm on the Java Card J-SAFE3 and STSAFE-J platforms exposing a 3.0.4 Java Card API. It is exploitable for STSAFE-J in closed...

UBUNTU-CVE-2021-20305

A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions GOST DSA, EDDSA & ECDSA result in the Elliptic Curve Cryptography point ECC multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allow...

PYSEC-2020-42

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a...
