CVE-2008-1147 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2025-04-09 N/A
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting.
CVE-2008-1148 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2025-04-09 N/A
A certain pseudo-random number generator (PRNG) algorithm that uses ADD with 0 random hops (aka "Algorithm A0"), as used in OpenBSD 3.5 through 4.2 and NetBSD 1.6.2 through 4.0, allows remote attackers to guess sensitive values such as (1) DNS transaction IDs or (2) IP fragmentation IDs by observing a sequence of previously generated values.

CVE-2007-0085 1 Openbsd 1 Openbsd 2025-04-09 N/A
Unspecified vulnerability in sys/dev/pci/vga_pci.c in the VGA graphics driver for wscons in OpenBSD 3.9 and 4.0, when the kernel is compiled with the PCIAGP option and a non-AGP device is being used, allows local users to gain privileges via unspecified vectors, possibly related to agp_ioctl NULL pointer reference.

Integer overflow in the fts_build function in fts.c in libc in (1) OpenBSD 4.4 and earlier and (2) Microsoft Interix 6.0 build 10.0.6030.0 allows context-dependent attackers to cause a denial of service (application crash) via a deep directory tree, related to the fts_level structure member, as demonstrated by (a) du, (b) rm, (c) chmod, and (d) chgrp on OpenBSD; and (e) SearchIndexer.exe on Vista Enterprise.
CVE-2009-0689 6 Freebsd, K-meleon Project, Mozilla and 3 more 9 Freebsd, K-meleon, Firefox and 6 more 2025-04-09 N/A
Array index error in the (1) dtoa implementation in dtoa.c (aka pdtoa.c) and the (2) gdtoa (aka new dtoa) implementation in gdtoa/misc.c in libc, as used in multiple operating systems and products including in FreeBSD 6.4 and 7.2, NetBSD 5.0, OpenBSD 4.5, Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4, K-Meleon 1.5.3, SeaMonkey 1.1.8, and other products, allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large precision value in the format argument to a printf function, which triggers incorrect memory allocation and a heap-based buffer overflow during conversion to a floating-point number.
CVE-2009-0780 1 Openbsd 1 Openbsd 2025-04-09 N/A
The aspath_prepend function in rde_attr.c in bgpd in OpenBSD 4.3 and 4.4 allows remote attackers to cause a denial of service (application crash) via an Autonomous System (AS) advertisement containing a long AS path.
CVE-2006-5550 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-09 N/A
The kernel in FreeBSD 6.1 and OpenBSD 4.0 allows local users to cause a denial of service via unspecified vectors involving certain ioctl requests to /dev/crypto.
CVE-2006-5218 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2025-04-09 N/A
Integer overflow in the systrace_preprepl function (STRIOCREPLACE) in systrace in OpenBSD 3.9 and NetBSD 3 allows local users to cause a denial of service (crash), gain privileges, or read arbitrary kernel memory via large numeric arguments to the systrace ioctl.
CVE-2006-6164 1 Openbsd 1 Openbsd 2025-04-09 N/A
The _dl_unsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LD_PRELOAD to loading processes, which might be leveraged to gain privileges.
CVE-2007-0343 1 Openbsd 1 Openbsd 2025-04-09 N/A
OpenBSD before 20070116 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via certain IPv6 ICMP (aka ICMP6) echo request packets.
CVE-2008-0384 1 Openbsd 1 Openbsd 2025-04-09 N/A
OpenBSD 4.2 allows local users to cause a denial of service (kernel panic) by calling the SIOCGIFRTLABEL IOCTL on an interface that does not have a route label, which triggers a NULL pointer dereference when the return value from the rtlabel_id2name function is not checked.
CVE-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 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-2000-0962 1 Openbsd 1 Openbsd 2025-04-03 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-1999-0674 3 Netbsd, Openbsd, Sun 4 Netbsd, Openbsd, Solaris and 1 more 2025-04-03 N/A
The BSD profil system call allows a local user to modify the internal data space of a program via profiling and execve.
CVE-2002-0765 1 Openbsd 2 Openbsd, Openssh 2025-04-03 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-2002-0701 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2025-04-03 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-2000-0914 1 Openbsd 1 Openbsd 2025-04-03 N/A
OpenBSD 2.6 and earlier allows remote attackers to cause a denial of service by flooding the server with ARP requests.

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-2002-0766 1 Openbsd 1 Openbsd 2025-04-03 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-2002-0557 1 Openbsd 1 Openbsd 2025-04-03 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().
