Gloria Zhao, Niklas Gögge, and b10c discuss 3 recently announced Bitcoin Core vulnerabilities:

- DoS vulnerability in headers sync

- DoS vulnerability in inventory send queue

- Crash vulnerability in compact block relay

High severity:

An attacker could provide a peer with a chain of low-difficulty headers, which could be used to remotely crash the node.

Medium severity:

Increased network activity affected block and transaction propagation and dropped connections.

High severity:

An attacker could remotely crash Bitcoin Core nodes by triggering an assertion in the blocktxn message handling logic.
