Prior to zebrad version 4.3.0 and zebra-chain version 6.0.1, a vulnerability in Zebra&#39;s transaction processing logic allows a remote, unauthenticated attacker to cause a Zebra node to panic (crash). This is triggered by sending a specially crafted V5 transaction that passes initial deserialization but fails during transaction ID calculation. This issue has been patched in zebrad version 4.3.0 and zebra-chain version 6.0.1.</p> <p>ZEBRA is a Zcash node written entirely in Rust.
