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-2006-0098 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM 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/.

Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.
CVE-2003-1366 1 Openbsd 1 Openbsd 2025-04-03 3.3 LOW N/A

CVE-2004-0218 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
isakmpd in OpenBSD 3.4 and earlier allows remote attackers to cause a denial of service (infinite loop) via an ISAKMP packet with a zero-length payload, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2001-1047 1 Openbsd 1 Openbsd 2025-04-03 1.2 LOW N/A
Race condition in OpenBSD VFS allows local users to cause a denial of service (kernel panic) by (1) creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or (2) calling dup2 on a file descriptor in one process, then setting the descriptor to NULL via a close in another process that is created via rfork.
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-1999-0001 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.
CVE-1999-0304 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2025-04-03 7.2 HIGH N/A
mmap function in BSD allows local attackers in the kmem group to modify memory through devices.
CVE-2002-2222 2 Freebsd, Openbsd 2 Ports Collection, Openbsd 2025-04-03 5.1 MEDIUM N/A
isakmpd/message.c in isakmpd in FreeBSD before isakmpd-20020403_1, and in OpenBSD 3.1, allows remote attackers to cause a denial of service (crash) by sending Internet Key Exchange (IKE) payloads out of sequence.
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-1999-0703 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2025-04-03 3.6 LOW N/A
OpenBSD, BSDI, and other Unix operating systems allow users to set chflags and fchflags on character and block devices.
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-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2025-04-03 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2006-4436 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM 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-2004-0084 2 Openbsd, Xfree86 Project 2 Openbsd, X11r6 2025-04-03 10.0 HIGH N/A
Buffer overflow in the ReadFontAlias function in XFree86 4.1.0 to 4.3.0, when using the CopyISOLatin1Lowered function, allows local or remote authenticated users to execute arbitrary code via a malformed entry in the font alias (font.alias) file, a different vulnerability than CVE-2004-0083 and CVE-2004-0106.
CVE-2004-0416 5 Cvs, Gentoo, Openbsd and 2 more 5 Cvs, Linux, Openbsd and 2 more 2025-04-03 10.0 HIGH N/A

CVE-2004-0171 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 5.0 MEDIUM N/A
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections.
CVE-2004-0819 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
The bridge functionality in OpenBSD 3.4 and 3.5, when running a gateway configured as a bridging firewall with the link2 option for IPSec enabled, allows remote attackers to cause a denial of service (crash) via an ICMP echo (ping) packet.
