+Subject: [PATCH] verify: fix signature verification (CVE-2022-24884)
+
+Verify that r and s are non-zero. Without these checks, an all-zero
+signature is always considered valid.
+
+While it would be nicer to error out in ecdsa_verify_prepare_legacy()
+already, that would require users of libecdsautil to check a return value
+of the prepare step. To be safe, implement the fix in an API/ABI-compatible
+way that doesn't need changes to the users.
