Exploit availability: Yes [Search exploit]Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack or access sensitive information.
The vulnerability exists due to integer overflow in the "SSH_MSG_DISCONNECT" logic in "packet.c" in a bounds check. A remote attacker can specify an arbitrary (out-of-bounds) offset for a subsequent memory read, trigger out-of-bounds read, disclose sensitive information or cause a denial of service condition on the target system when a user connects to the malicious SSH server.
