CVE-2006-6730 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-09 N/A
OpenBSD and NetBSD permit usermode code to kill the display server and write to the X.Org /dev/xf86 device, which allows local users with root privileges to reduce securelevel by replacing the System Management Mode (SMM) handler via a write to an SMRAM address within /dev/xf86 (aka the video card memory-mapped I/O range), and then launching the new handler via a System Management Interrupt (SMI), as demonstrated by a write to Programmed I/O port 0xB2.
CVE-2007-5365 5 Debian, Openbsd, Redhat and 2 more 7 Debian Linux, Openbsd, Enterprise Linux and 4 more 2025-04-09 N/A
Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.
CVE-2002-1220 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2025-04-03 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-2002-0765 1 Openbsd 2 Openbsd, Openssh 2025-04-03 N/A
sshd in OpenSSH 3.2.2, when using YP with netgroups and under certain conditions, may allow users to successfully authenticate and log in with another user's password.
CVE-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 N/A
Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.
CVE-2000-0489 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 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-2002-0542 1 Openbsd 1 Openbsd 2025-04-03 N/A
mail in OpenBSD 2.9 and 3.0 processes a tilde (~) escape character in a message even when it is not in interactive mode, which could allow local users to gain root privileges via calls to mail in cron.
CVE-2002-0381 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 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-2000-0962 1 Openbsd 1 Openbsd 2025-04-03 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-1999-0674 3 Netbsd, Openbsd, Sun 4 Netbsd, Openbsd, Solaris and 1 more 2025-04-03 N/A
The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve.
CVE-2006-4435 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD 3.8, 3.9, and possibly earlier versions allows context-dependent attackers to cause a denial of service (kernel panic) by allocating more semaphores than the default.
CVE-2001-1559 1 Openbsd 1 Openbsd 2025-04-03 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-2006-4436 1 Openbsd 1 Openbsd 2025-04-03 N/A
isakmpd in OpenBSD 3.8, 3.9, and possibly earlier versions, creates Security Associations (SA) with a replay window of size 0 when isakmpd acts as a responder during SA negotiation, which allows remote attackers to replay IPSec packets and bypass the replay protection.
CVE-2001-1415 1 Openbsd 1 Openbsd 2025-04-03 N/A
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes.
CVE-2000-0914 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests.
CVE-2006-0098 1 Openbsd 1 Openbsd 2025-04-03 N/A
The dupfdopen function in sys/kern/kern_descrip.c in OpenBSD 3.7 and 3.8 allows local users to re-open arbitrary files by using setuid programs to access file descriptors using /dev/fd/.
CVE-2001-0670 5 Bsd, Freebsd, Netbsd and 2 more 5 Bsd, Freebsd, Netbsd and 2 more 2025-04-03 N/A
Buffer overflow in BSD line printer daemon (in.lpd or lpd) in various BSD-based operating systems allows remote attackers to execute arbitrary code via an incomplete print job followed by a request to display the printer queue.
CVE-2005-0960 1 Openbsd 1 Openbsd 2025-04-03 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-2005-0740 1 Openbsd 1 Openbsd 2025-04-03 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-2001-0378 1 Openbsd 1 Openbsd 2025-04-03 N/A
readline prior to 4.1, in OpenBSD 2.8 and earlier, creates history files with insecure permissions, which allows a local attacker to recover potentially sensitive information via readline history files.
