CVE-2002-0514 1 Openbsd 1 Openbsd 2026-04-16 N/A
PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128 in the RST packet, which allows remote attackers to determine if a port is being filtered because the TTL is different than the default TTL.
CVE-2005-2798 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts.
CVE-2005-2797 1 Openbsd 1 Openssh 2026-04-16 N/A
OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality.
CVE-2002-0414 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
KAME-derived implementations of IPsec on NetBSD 1.5.2, FreeBSD 4.5, and other operating systems, does not properly consult the Security Policy Database (SPD), which could cause a Security Gateway (SG) that does not use Encapsulating Security Payload (ESP) to forward forged IPv4 packets.
CVE-2000-0962 1 Openbsd 1 Openbsd 2026-04-16 N/A
The IPSEC implementation in OpenBSD 2.7 does not properly handle empty AH/ESP packets, which allows remote attackers to cause a denial of service.
CVE-2005-2666 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
SSH, as implemented in OpenSSH before 4.0 and possibly other implementations, stores hostnames, IP addresses, and keys in plaintext in the known_hosts file, which makes it easier for an attacker that has compromised an SSH user's account to generate a list of additional targets that are more likely to have the same password or key.
CVE-2005-0960 1 Openbsd 1 Openbsd 2026-04-16 N/A
Multiple vulnerabilities in the SACK functionality in (1) tcp_input.c and (2) tcp_usrreq.c OpenBSD 3.5 and 3.6 allow remote attackers to cause a denial of service (memory exhaustion or system crash).
CVE-2002-0381 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
The TCP implementation in various BSD operating systems (tcp_input.c) does not properly block connections to broadcast addresses, which could allow remote attackers to bypass intended filters via packets with a unicast link layer address and an IP broadcast address.
CVE-2005-0740 1 Openbsd 1 Openbsd 2026-04-16 N/A
The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout.
CVE-2004-2760 1 Openbsd 1 Openssh 2026-04-16 N/A
sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.
CVE-2000-0751 3 Netbsd, Openbsd, Redhat 3 Netbsd, Openbsd, Linux 2026-04-16 N/A
mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.
CVE-1999-0727 1 Openbsd 1 Openbsd 2026-04-16 N/A
A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted.
CVE-1999-0304 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2026-04-16 N/A
mmap function in BSD allows local attackers in the kmem group to modify memory through devices.
CVE-1999-0001 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2026-04-16 N/A
ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
CVE-2004-2338 1 Openbsd 1 Openbsd 2026-04-16 N/A
OpenBSD 3.3 and 3.4 does not properly parse Accept and Deny rules without netmasks on big-endian 64-bit platforms such as SPARC64, which may allow remote attackers to bypass access restrictions.
CVE-2004-2230 1 Openbsd 1 Openbsd 2026-04-16 N/A
Heap-based buffer overflow in isakmpd on OpenBSD 3.4 through 3.6 allows local users to cause a denial of service (panic) and corrupt memory via IPSEC credentials on a socket.
CVE-2004-2163 1 Openbsd 1 Openbsd 2026-04-16 N/A
login_radius on OpenBSD 3.2, 3.5, and possibly other versions does not verify the shared secret in a response packet from a RADIUS server, which allows remote attackers to bypass authentication by spoofing server replies.
CVE-2004-1799 1 Openbsd 1 Openbsd 2026-04-16 N/A
PF in certain OpenBSD versions, when stateful filtering is enabled, does not limit packets for a session to the original interface, which allows remote attackers to bypass intended packet filters via spoofed packets to other interfaces.
CVE-2001-1559 1 Openbsd 1 Openbsd 2026-04-16 5.5 Medium
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
CVE-2000-0750 3 Netbsd, Openbsd, Redhat 3 Netbsd, Openbsd, Linux 2026-04-16 N/A
Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.
