For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.\n\ud83d\udccf Published: 2025-02-28T21:25:28.861Z\n\ud83d\udccf Modified: 2025-04-10T23:10:06.357Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/security/cve/CVE-2025-26466\n2. https://bugzilla.redhat.com/show_bug.cgi?id=2345043\n3. https://www.qualys.com/2025/02/18/openssh-mitm-dos.txt", "creation_timestamp": "2025-04-10T23:49:31.000000Z"}
