CVE-2001-1244 7 Freebsd, Hp, Linux and 4 more 9 Freebsd, Hp-ux, Vvos and 6 more 2025-04-03 5.0 MEDIUM 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-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 7.2 HIGH 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-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2025-04-03 5.0 MEDIUM 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-2002-0557 1 Openbsd 1 Openbsd 2025-04-03 7.5 HIGH N/A
Vulnerability in OpenBSD 3.0, when using YP with netgroups in the password database, causes (1) rexec or (2) rsh to run another user's shell, or (3) atrun to change to a different user's directory, possibly due to memory allocation failures or an incorrect call to auth_approval().
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-2000-0962 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM 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-2002-2188 1 Openbsd 1 Openbsd 2025-04-03 4.9 MEDIUM 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-2002-0765 1 Openbsd 2 Openbsd, Openssh 2025-04-03 7.5 HIGH 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-2004-0220 1 Openbsd 1 Openbsd 2025-04-03 10.0 HIGH N/A
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service via an ISAKMP packet with a malformed Cert Request payload, which causes an integer underflow that is used in a malloc operation that is not properly handled, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2004-0482 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM 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-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-2004-2230 1 Openbsd 1 Openbsd 2025-04-03 2.1 LOW 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-2001-1145 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 6.2 MEDIUM 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-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-2001-0247 5 Freebsd, Mit, Netbsd and 2 more 5 Freebsd, Kerberos 5, Netbsd and 2 more 2025-04-03 10.0 HIGH N/A
Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
CVE-1999-0061 4 Bsdi, Freebsd, Linux and 1 more 4 Bsd Os, Freebsd, Linux Kernel and 1 more 2025-04-03 5.1 MEDIUM N/A
File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).

Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line.
CVE-1999-0001 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
ip_input.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
