CVE-1999-0481 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
Denial of service in "poll" in OpenBSD.
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-2000-0310 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM 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-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-2002-1221 3 Freebsd, Isc, Openbsd 3 Freebsd, Bind, Openbsd 2025-04-03 5.0 MEDIUM N/A
BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.
CVE-1999-0724 1 Openbsd 1 Openbsd 2025-04-03 4.6 MEDIUM N/A
Buffer overflow in OpenBSD procfs and fdescfs file systems via uio_offset in the readdir() function.
CVE-2001-1559 1 Openbsd 1 Openbsd 2025-04-03 2.1 LOW 5.5 MEDIUM
The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.
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-2004-0219 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 (crash) via an ISAKMP packet with a malformed IPSEC SA payload, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 2.1 LOW N/A
ktrace in BSD-based operating systems allows the owner of a process with special privileges to trace the process after its privileges have been lowered, which may allow the owner to obtain sensitive information that the process obtained while it was running with the extra privileges.
CVE-2004-0222 1 Openbsd 1 Openbsd 2025-04-03 5.0 MEDIUM N/A
Multiple memory leaks in isakmpd in OpenBSD 3.4 and earlier allow remote attackers to cause a denial of service (memory exhaustion) via certain ISAKMP packets, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2003-0144 4 Bsd, Freebsd, Lprold and 1 more 4 Lpr, Freebsd, Lprold and 1 more 2025-04-03 7.2 HIGH N/A
Buffer overflow in the lprm command in the lprold lpr package on SuSE 7.1 through 7.3, OpenBSD 3.2 and earlier, and possibly other operating systems, allows local users to gain root privileges via long command line arguments such as (1) request ID or (2) user name.
CVE-2005-4351 4 Dragonfly, Freebsd, Linux and 1 more 4 Dragonfly, Freebsd, Linux Kernel and 1 more 2025-04-03 4.3 MEDIUM 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-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-1999-0396 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-03 2.6 LOW N/A
A race condition between the select() and accept() calls in NetBSD TCP servers allows remote attackers to cause a denial of service.
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-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-2001-0378 1 Openbsd 1 Openbsd 2025-04-03 2.1 LOW N/A
readline prior to 4.1, in OpenBSD 2.8 and earlier, creates history files with insecure permissions, which allows a local attacker to recover potentially sensitive information via readline history files.
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-2000-0995 1 Openbsd 1 Openbsd 2025-04-03 7.2 HIGH N/A
Format string vulnerability in OpenBSD yp_passwd program (and possibly other BSD-based operating systems) allows attackers to gain root privileges a malformed name.
