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-2001-1415 1 Openbsd 1 Openbsd 2026-04-16 N/A
vi.recover in OpenBSD before 3.1 allows local users to remove arbitrary zero-byte files such as device nodes.
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-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-2003-0804 3 Apple, Freebsd, Openbsd 4 Mac Os X, Mac Os X Server, Freebsd and 1 more 2026-04-16 N/A
The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.
CVE-2003-0682 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Linux 2026-04-16 N/A
"Memory bugs" in OpenSSH 3.7.1 and earlier, with unknown impact, a different set of vulnerabilities than CVE-2003-0693 and CVE-2003-0695.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 7.5 High
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
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-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-2000-0312 1 Openbsd 1 Openbsd 2026-04-16 N/A
cron in OpenBSD 2.5 allows local users to gain root privileges via an argv[] that is not NULL terminated, which is passed to cron's fake popen function.
CVE-1999-0052 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2026-04-16 7.5 High
IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.
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-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-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-2004-0114 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2026-04-16 N/A
The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.
CVE-2004-0221 1 Openbsd 1 Openbsd 2026-04-16 N/A
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with a delete payload containing a large number of SPIs, which triggers an out-of-bounds read error, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2002-2180 1 Openbsd 1 Openbsd 2026-04-16 N/A
The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.
CVE-2002-2188 1 Openbsd 1 Openbsd 2026-04-16 N/A
OpenBSD before 3.2 allows local users to cause a denial of service (kernel crash) via a call to getrlimit(2) with invalid arguments, possibly due to an integer signedness error.
CVE-2004-1653 1 Openbsd 1 Openssh 2026-04-16 N/A
The default configuration for OpenSSH enables AllowTcpForwarding, which could allow remote authenticated users to perform a port bounce, when configured with an anonymous access program such as AnonCVS.
CVE-2025-61984 1 Openbsd 1 Openssh 2026-04-15 3.6 Low
ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.)
