The sshd-sftp component provides support for SFTP.\n\n\n\n\nThe SFTP client implementation, when receiving a reply, did not check that this reply corresponded to a request sent earlier. Unsolicited replies would be stored but never consumed. A malicious server could keep sending unsolicited replies until available memory in the client was exhausted.\n\n\n\n\nUsers are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0.9.0"}, {"fixed": "2.20.0"}]}, {"type": "SEMVER", "events": [{"introduced": "3.0.0-M1"}, {"fixed": "3.0.0-M6"}]}]}], "references": [{"type": "WEB", "url": "https://lists.apache.org/thread.html/x2cb00kh4qvsq145tj2w4g3toy8cybld"}]}
