|---|---|---|---|---|
| CVE-2026-57589 | 1 Openbsd | 1 Openbsd | 2026-06-25 | 7.4 High |
| sys/kern/sysv_sem.c in OpenBSD through 7.9 has a use-after-free allowing local privilege escalation to root. This is a context switch use-after-free after tsleep in sys_semget(). | ||||
| CVE-2026-55706 | 1 Openbsd | 1 Openbsd | 2026-06-17 | 5.8 Medium |
| sppp_pap_input in sys/net/if_spppsubr.c in OpenBSD before 076e2b1 allows authentication bypass via certain zero values for lengths. | ||||
| CVE-2026-41285 | 1 Openbsd | 1 Openbsd | 2026-04-28 | 4.3 Medium |
| In OpenBSD through 7.8, the slaacd and rad daemons have an infinite loop when they receive a crafted ICMPv6 Neighbor Discovery (ND) option (over a local network) with length zero, because of an "nd_opt_len * 8 - 2" expression with no preceding check for whether nd_opt_len is zero. | ||||
| CVE-2007-0343 | 1 Openbsd | 1 Openbsd | 2026-04-23 | 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-2007-1365 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| Buffer overflow in kern/uipc_mbuf2.c in OpenBSD 3.9 and 4.0 allows remote attackers to execute arbitrary code via fragmented IPv6 packets due to "incorrect mbuf handling for ICMP6 packets." NOTE: this was originally reported as a denial of service. | ||||
| CVE-2008-2476 | 6 Force10, Freebsd, Juniper and 3 more | 6 Ftos, Freebsd, Jnos and 3 more | 2026-04-23 | N/A |
| The IPv6 Neighbor Discovery Protocol (NDP) implementation in (1) FreeBSD 6.3 through 7.1, (2) OpenBSD 4.2 and 4.3, (3) NetBSD, (4) Force10 FTOS before E7.7.1.1, (5) Juniper JUNOS, and (6) Wind River VxWorks 5.x through 6.4 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB). | ||||
| CVE-2007-6700 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| Cross-site scripting (XSS) vulnerability in cgi-bin/bgplg in the web interface for the BGPD daemon in OpenBSD 4.1 allows remote attackers to inject arbitrary web script or HTML via the cmd parameter. | ||||
| CVE-2008-1147 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2026-04-23 | 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-2007-2242 | 5 Freebsd, Ietf, Netbsd and 2 more | 5 Freebsd, Ipv6, Netbsd and 2 more | 2026-04-23 | N/A |
| The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers. | ||||
| CVE-2008-1215 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| Stack-based buffer overflow in the command_Expand_Interpret function in command.c in ppp (aka user-ppp), as distributed in FreeBSD 6.3 and 7.0, OpenBSD 4.1 and 4.2, and the net/userppp package for NetBSD, allows local users to gain privileges via long commands containing "~" characters. | ||||
| CVE-2008-4247 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| ftpd in OpenBSD 4.3, FreeBSD 7.0, NetBSD 4.0, Solaris, and possibly other operating systems interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser. | ||||
| CVE-2009-3572 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| OpenBSD 4.4, 4.5, and 4.6, when running on an i386 kernel, does not properly handle XMM exceptions, which allows local users to cause a denial of service (kernel panic) via unspecified vectors. | ||||
| CVE-2008-4609 | 12 Bsd, Bsdi, Cisco and 9 more | 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more | 2026-04-23 | N/A |
| The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. | ||||
| CVE-2006-6397 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2026-04-23 | N/A |
| Integer overflow in banner/banner.c in FreeBSD, NetBSD, and OpenBSD might allow local users to modify memory via a long banner. NOTE: CVE and multiple third parties dispute this issue. Since banner is not setuid, an exploit would not cross privilege boundaries in normal operations. This issue is not a vulnerability | ||||
| CVE-2009-0537 | 2 Microsoft, Openbsd | 2 Interix, Openbsd | 2026-04-23 | N/A |
| 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-2008-1146 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2026-04-23 | N/A |
| A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND. | ||||
| CVE-2009-0689 | 6 Freebsd, K-meleon Project, Mozilla and 3 more | 9 Freebsd, K-meleon, Firefox and 6 more | 2026-04-23 | 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-2008-1057 | 1 Openbsd | 1 Openbsd | 2026-04-23 | N/A |
| The ip6_check_rh0hdr function in netinet6/ip6_input.c in OpenBSD 4.2 allows attackers to cause a denial of service (panic) via malformed IPv6 routing headers. | ||||
| CVE-2008-1148 | 8 Apple, Cosmicperl, Darwin and 5 more | 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more | 2026-04-23 | 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. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning, injection into TCP packets, and OS fingerprinting. | ||||
| CVE-2007-4305 | 5 Netbsd, Openbsd, Sysjail and 2 more | 5 Netbsd, Openbsd, Sysjail and 2 more | 2026-04-23 | N/A |
| Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing. | ||||
