libsecp256k1: Flaw in Scalar::check_overflow allows side-channel timing attackVersions of libsecp256k1 prior to 0.3.1 did not execute
Scalar::check_overflow in constant time.
This allows an attacker to potentially leak information via a timing attack.
The flaw was corrected by modifying Scalar::check_overflow to execute in constant time.
libsecp256k1: libsecp256k1 allows overflowing signatureslibsecp256k1 accepts signatures whose R or S parameter is larger than the secp256k1 curve order, which differs from other implementations. This could lead to invalid signatures being verified.
The error is resolved in 0.5.0 by adding a check_overflow flag.
