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-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-2001-1380 2 Openbsd, Redhat 2 Openssh, Linux 2026-04-16 N/A
OpenSSH before 2.9.9, while using keypairs and multiple keys of different types in the ~/.ssh/authorized_keys2 file, may not properly handle the "from" option associated with a key, which could allow remote attackers to login from unauthorized IP addresses.
CVE-2002-0391 5 Freebsd, Microsoft, Openbsd and 2 more 9 Freebsd, Windows 2000, Windows Nt and 6 more 2026-04-16 9.8 Critical
Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
CVE-1999-0481 1 Openbsd 1 Openbsd 2026-04-16 N/A
Denial of service in "poll" in OpenBSD.
CVE-2002-1220 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2026-04-16 N/A
BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.
CVE-1999-0396 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2026-04-16 N/A
A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service.
CVE-1999-1010 1 Openbsd 1 Openssh 2026-04-16 N/A
An SSH 1.2.27 server allows a client to use the "none" cipher, even if it is not allowed by the server policy.
CVE-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories.
CVE-2004-0175 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2026-04-16 N/A
Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992.
CVE-2003-0955 1 Openbsd 1 Openbsd 2026-04-16 N/A
OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow.
CVE-2003-0787 1 Openbsd 1 Openssh 2026-04-16 N/A
The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges.
CVE-2004-0482 1 Openbsd 1 Openbsd 2026-04-16 N/A
Multiple integer overflows in (1) procfs_cmdline.c, (2) procfs_fpregs.c, (3) procfs_linux.c, (4) procfs_regs.c, (5) procfs_status.c, and (6) procfs_subr.c in procfs for OpenBSD 3.5 and earlier allow local users to read sensitive kernel memory and possibly perform other unauthorized activities.
CVE-2000-0310 1 Openbsd 1 Openbsd 2026-04-16 N/A
IP fragment assembly in OpenBSD 2.4 allows a remote attacker to cause a denial of service by sending a large number of fragmented packets.
CVE-2000-0309 1 Openbsd 1 Openbsd 2026-04-16 N/A
The i386 trace-trap handling in OpenBSD 2.4 with DDB enabled allows a local user to cause a denial of service.
CVE-2003-0786 1 Openbsd 1 Openssh 2026-04-16 N/A
The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges.
CVE-2000-0996 1 Openbsd 1 Openbsd 2026-04-16 N/A
Format string vulnerability in OpenBSD su program (and possibly other BSD-based operating systems) allows local attackers to gain root privileges via a malformed shell.
CVE-2000-0489 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers.
CVE-2001-1459 1 Openbsd 1 Openssh 2026-04-16 N/A
OpenSSH 2.9 and earlier does not initiate a Pluggable Authentication Module (PAM) session if commands are executed with no pty, which allows local users to bypass resource limits (rlimits) set in pam.d.
CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2026-04-16 N/A
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.
