A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

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.

An improper neutralization of special elements used in an OS Command vulnerability [CWE-78] in FortiSandbox may allow an authenticated attacker with at least read-only permission to execute unauthorized commands via crafted requests.

A Use of Hard-coded Cryptographic Key vulnerability [CWE-321] in FortiSandbox may allow a privileged attacker with super-admin profile and CLI access to read sensitive data via CLI.

A client-side enforcement of server-side security vulnerability [CWE-602] in Fortinet FortiSandbox version 5.0.0, 4.4.0 through 4.4.6 and before 4.2.7 allows an authenticated attacker with at least read-only permission to execute unauthorized commands via crafted requests.
