Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Cryptographic Issue: Incomplete enforcement of ECDSA signature constraints allows for signature malleability, where an attacker can modify a valid signature into another valid signature without knowing the private key.

Crypto Implementation Issue: Using incorrect constants (such as decimal 80 instead of hexadecimal 0x80) during DER serialization of ECDSA signature fields can result in malformed signatures or parser-specific validation bypasses.
