GHSA-X3FF-W252-2G7J StableLib Ed25519 Signature Malleability via Missing S < L Check
Ed25519 Signature Malleability via Missing S = L to prevent signature malleability. When S = L, SB = S mod LB = S - LB, meaning two different 32-byte S values produce the same verification result. An attacker who observes a valid signature R, S can produce a second valid signature R, S + L for th...
