A flaw was found in the OpenSSH package. 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.

A client-side enforcement of server-side security vulnerability [CWE-602] in FortiSandbox may allow an authenticated attacker with at least read-only permission to download or upload configuration.
