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-2001-0554 10 Debian, Freebsd, Ibm and 7 more 12 Debian Linux, Freebsd, Aix and 9 more 2026-04-16 N/A
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
CVE-1999-0323 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2026-04-16 N/A
FreeBSD mmap function allows users to modify append-only or immutable files.
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-2006-0883 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 N/A
OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting.
CVE-2000-0313 1 Openbsd 1 Openbsd 2026-04-16 N/A
Vulnerability in OpenBSD 2.6 allows a local user to change interface media configurations.
CVE-1999-0485 1 Openbsd 1 Openbsd 2026-04-16 N/A
Remote attackers can cause a system crash through ipintr() in ipq in OpenBSD.
CVE-1999-0483 1 Openbsd 1 Openbsd 2026-04-16 N/A
OpenBSD crash using nlink value in FFS and EXT2FS filesystems.
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.
CVE-2006-4436 1 Openbsd 1 Openbsd 2026-04-16 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-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-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-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-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-2001-1029 2 Freebsd, Openbsd 2 Freebsd, Openssh 2026-04-16 N/A
libutil in OpenSSH on FreeBSD 4.4 and earlier does not drop privileges before verifying the capabilities for reading the copyright and welcome files, which allows local users to bypass the capabilities checks and read arbitrary files by specifying alternate copyright or welcome files.
CVE-1999-0724 1 Openbsd 1 Openbsd 2026-04-16 N/A
Buffer overflow in OpenBSD procfs and fdescfs file systems via uio_offset in the readdir() function.
CVE-2005-4351 4 Dragonfly, Freebsd, Linux and 1 more 4 Dragonfly, Freebsd, Linux Kernel and 1 more 2026-04-16 N/A
The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running.
CVE-2005-0356 9 Alaxala, Cisco, F5 and 6 more 76 Alaxala Networks, Agent Desktop, Aironet Ap1200 and 73 more 2026-04-16 N/A
Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.
CVE-2002-0640 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2026-04-16 N/A
Buffer overflow in sshd in OpenSSH 2.3.1 through 3.3 may allow remote attackers to execute arbitrary code via a large number of responses during challenge response authentication when OpenBSD is using PAM modules with interactive keyboard authentication (PAMAuthenticationViaKbdInt).
CVE-2006-4304 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver.
