OpenSSL Flaw Exposes Servers to Memory Exhaustion Attacks

A newly discovered OpenSSL flaw, dubbed HollowByte, leaves unpatched servers vulnerable to memory exhaustion attacks, where a mere 11 bytes can trigger the allocation of up to 131 KB of memory for a message that never arrives. This tiny trigger can bring a server to its knees, freezing memory and blocking critical connections.
