HollowByte: 11-Byte Payload Triggers Memory Bloat DoS on OpenSSL Servers

HollowByte is an OpenSSL denial-of-service vulnerability that allows an unauthenticated attacker to trigger excessive memory allocation with a crafted 11‑byte TLS packet, potentially causing processes to be killed or become unresponsive; operators should urgently apply OpenSSL patches, restart affected services, and implement rate limiting, connection throttling, and TLS termination behind proxies or CDNs as mitigations.
