CVE-2020-15522

Bouncy Castle BC Java before 1.66, BC C .NET before 1.8.7, BC-FJA before 1.0.1.2, 1.0.2.1, and BC-FNA before 1.0.1.1 have a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multip...

Important: nettle

Issue Overview: A flaw was found in Nettle, 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 allows an...

CVE-2021-20305

CVE-2021-20305 affects Nettle prior to 3.7.2 where signature verification (GOST DSA, EDDSA, ECDSA) calls ECC multiply with out-of-range scalars, potentially producing incorrect results and allowing an attacker to force an invalid signature (leading to assertion failure or validation issues). Docu...

FreeBSD : nettle 3.7.2 -- fix serious ECDSA signature verify bug (80f9dbd3-8eec-11eb-b9e8-3525f51429a0)

Niels Moller reports : I've prepared a new bug-fix release of Nettle, a low-level cryptographics library, to fix a serious bug in the function to verify ECDSA signatures. Implications include an assertion failure, which could be used for denial-of-service, when verifying signatures on the secp224...
