Heap buffer overflow in the server site handshake implementation in Real Time Logic LLC's SharkSSL version (from 05/05/24) commit 64808a5e12c83b38f85c943dee0112e428dc2a43 allows a remote attacker to trigger a Denial-of-Service via a malformed Client-Hello message.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
