CVE-2001-0284 1 Openbsd 1 Openbsd 2025-04-03 10.0 HIGH N/A
Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option.
CVE-2002-0381 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 5.0 MEDIUM 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-2000-0994 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Format string vulnerability in OpenBSD fstat program (and possibly other BSD-based operating systems) allows local users to gain root privileges via the PWD environmental variable.
CVE-2004-2163 1 Openbsd 1 Openbsd 2025-04-03 7.5 HIGH 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-1999-0323 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2025-04-03 10.0 HIGH N/A
FreeBSD mmap function allows users to modify append-only or immutable files.
CVE-2001-1415 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM N/A
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes.
CVE-2000-0217 2 Openbsd, Ssh 3 Openssh, Ssh, Ssh2 2025-04-03 5.1 MEDIUM N/A
The default configuration of SSH allows X forwarding, which could allow a remote attacker to control a client's X sessions via a malicious xauth program.
CVE-2002-0572 3 Freebsd, Openbsd, Sun 4 Freebsd, Openbsd, Solaris and 1 more 2025-04-03 7.2 HIGH N/A
FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files.
CVE-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 6 Tru64, Freebsd, Openbsd and 3 more 2025-04-03 5.0 MEDIUM N/A
The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
CVE-2003-1562 1 Openbsd 1 Openssh 2025-04-03 7.6 HIGH N/A
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
CVE-2003-0693 1 Openbsd 1 Openssh 2025-04-03 10.0 HIGH N/A
A "buffer management error" in buffer_append_space of buffer.c for OpenSSH before 3.7 may allow remote attackers to execute arbitrary code by causing an incorrect amount of memory to be freed and corrupting the heap, a different vulnerability than CVE-2003-0695.
CVE-2003-0955 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM 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-1999-0305 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
The system configuration control (sysctl) facility in BSD based operating systems OpenBSD 2.2 and earlier, and FreeBSD 2.2.5 and earlier, does not properly restrict source routed packets even when the (1) dosourceroute or (2) forwarding variables are set, which allows remote attackers to spoof TCP connections.
CVE-2000-0995 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Format string vulnerability in OpenBSD yp_passwd program (and possibly other BSD-based operating systems) allows attackers to gain root privileges a malformed name.
CVE-2000-0309 1 Openbsd 1 Openbsd 2025-04-03 2.1 LOW 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-2002-1915 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 2.1 LOW 5.5 MEDIUM
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.
CVE-1999-0052 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 5.0 MEDIUM 7.5 HIGH
IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.
CVE-2002-0083 9 Conectiva, Engardelinux, Immunix and 6 more 11 Linux, Secure Linux, Immunix and 8 more 2025-04-03 10.0 HIGH 9.8 CRITICAL
Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.
CVE-2003-0144 4 Bsd, Freebsd, Lprold and 1 more 4 Lpr, Freebsd, Lprold and 1 more 2025-04-03 7.2 HIGH N/A
Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.
CVE-2003-0386 1 Openbsd 1 Openssh 2025-04-03 7.5 HIGH N/A
OpenSSH 3.6.1 and earlier, when restricting host access by numeric IP addresses and with VerifyReverseMapping disabled, allows remote attackers to bypass "from=" and "user@host" address restrictions by connecting to a host from a system whose reverse DNS hostname contains the numeric IP address.
