A heap-based buffer overflow vulnerability [CWE-122] in FortiOS, FortiManager, FortiAnalyzer, FortiManager Cloud, FortiAnalyzer Cloud, FortiProxy fgfmd daemon may allow an authenticated attacker to execute arbitrary code or commands via specifically crafted requests.
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.
