Technical details
The DefaultSftpClient implementation in the sshd-sftp component fails to validate that received SFTP replies correspond to prior requests, causing unsolicited replies to accumulate in client memory. An attacker controlling a malicious SFTP server can continuously send crafted unsolicited replies over the network to exhaust available heap memory in connecting clients. Fixed in versions 2.20.0 and 3.0.0-M6.
