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.
Multiple cross-site request forgery (CSRF) weaknesses [CWE-352] vulnerability in Fortinet FortiAIOps 2.0.0 may allow an unauthenticated remote attacker to perform arbitrary actions on behalf of an authenticated user via tricking the victim to execute malicious GET requests.
An improper neutralization of formula elements in a CSV File [CWE-1236] vulnerability in Fortinet FortiAIOps 2.0.0 may allow a remote authenticated attacker to execute arbitrary commands on a client's workstation via poisoned CSV reports.
Multiple insufficient session expiration weaknesses [CWE-613] vulnerability in Fortinet FortiAIOps 2.0.0 may allow an attacker to re-use stolen old session tokens to perform unauthorized operations via crafted requests.
Multiple Exposure of sensitive information to an unauthorized actor weaknesses [CWE-200] vulnerability in Fortinet FortiAIOps 2.0.0 may allow an authenticated, remote attacker to retrieve sensitive information from the API endpoint or log files.
CVE-2025-26466A 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.
CVE-2024-6387 A signal handler race condition was found in OpenSSH's server (sshd), where a client does not authenticate within LoginGraceTime seconds (120 by default, 600 in old OpenSSH versions), then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). This could lead to remote code execution with root privileges.
