nettle: Out of bounds memory access in signature verification

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 attacker to force an...

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 allows an attacker to force an invalid signature causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality integrity as well as system availability.
