CVE-2002-1420 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
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-2001-0554 9 Debian, Freebsd, Ibm and 6 more 11 Debian Linux, Freebsd, Aix and 8 more 2025-04-03 10.0 HIGH 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-2004-0688 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2025-04-03 7.5 HIGH N/A
Multiple integer overflows in (1) the xpmParseColors function in parse.c, (2) XpmCreateImageFromXpmImage, (3) CreateXImage, (4) ParsePixels, and (5) ParseAndPutPixels for libXpm before 6.8.1 may allow remote attackers to execute arbitrary code via a malformed XPM image file.
CVE-2003-1366 1 Openbsd 1 Openbsd 2025-04-03 3.3 LOW N/A
chpass in OpenBSD 2.0 through 3.2 allows local users to read portions of arbitrary files via a hard link attack on a temporary file used to store user database information.
CVE-2005-0960 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM 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 5.0 MEDIUM 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-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-2004-0492 5 Apache, Hp, Ibm and 2 more 7 Http Server, Virtualvault, Vvos and 4 more 2025-04-03 10.0 HIGH N/A
Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.
CVE-1999-0727 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted.
CVE-2000-0750 3 Netbsd, Openbsd, Redhat 3 Netbsd, Openbsd, Linux 2025-04-03 7.5 HIGH N/A
Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name.
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-2002-0766 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
OpenBSD 2.9 through 3.1 allows local users to cause a denial of service (resource exhaustion) and gain root privileges by filling the kernel's file descriptor table and closing file descriptors 0, 1, or 2 before executing a privileged process, which is not properly handled when OpenBSD fails to open an alternate descriptor.
CVE-2001-0284 1 Openbsd 1 Openbsd 2025-04-03 10.0 HIGH N/A
Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option.
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-2000-0994 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Format string vulnerability in OpenBSD fstat program (and possibly other BSD-based operating systems) allows local users to gain root privileges via the PWD environmental variable.
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-1999-0323 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2025-04-03 10.0 HIGH N/A

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-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.
