CVE-2004-0222 1 Openbsd 1 Openbsd 2024-01-26 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-2011-2168 1 Openbsd 1 Openbsd 2023-11-07 5.0 MEDIUM N/A
Multiple integer overflows in the glob implementation in libc in OpenBSD before 4.9 might allow context-dependent attackers to have an unspecified impact via a crafted string, related to the GLOB_APPEND and GLOB_DOOFFS flags, a different issue than CVE-2011-0418.
CVE-2009-0537 2 Microsoft, Openbsd 2 Interix, Openbsd 2023-11-07 4.9 MEDIUM 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-2008-1147 8 Apple, Cosmicperl, Darwin and 5 more 9 Mac Os X, Mac Os X Server, Directory Pro and 6 more 2023-11-07 6.8 MEDIUM 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-2007-6700 1 Openbsd 1 Openbsd 2023-11-07 4.3 MEDIUM 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-2004-0492 5 Apache, Hp, Ibm and 2 more 7 Http Server, Virtualvault, Vvos and 4 more 2023-11-07 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-2000-0489 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2023-11-07 2.1 LOW N/A
FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers.
CVE-2023-35784 1 Openbsd 2 Libressl, Openbsd 2023-11-06 N/A 9.8 CRITICAL
A double free or use after free could occur after SSL_clear in OpenBSD 7.2 before errata 026 and 7.3 before errata 004, and in LibreSSL before 3.6.3 and 3.7.x before 3.7.3. NOTE: OpenSSL is not affected.
CVE-2023-40216 1 Openbsd 1 Openbsd 2023-08-23 N/A 5.5 MEDIUM
OpenBSD 7.3 before errata 014 is missing an argument-count bounds check in console terminal emulation. This could cause incorrect memory access and a kernel crash after receiving crafted DCS or CSI terminal escape sequences.
CVE-2019-14899 4 Apple, Freebsd, Linux and 1 more 8 Ipados, Iphone Os, Mac Os X and 5 more 2023-03-01 4.9 MEDIUM 7.4 HIGH
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel.
CVE-2011-1013 2 Linux, Openbsd 2 Linux Kernel, Openbsd 2023-02-13 7.2 HIGH N/A
Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument.
CVE-2019-19726 1 Openbsd 1 Openbsd 2023-01-30 7.2 HIGH 7.8 HIGH
OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root.
CVE-2004-0687 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2023-01-20 7.5 HIGH N/A
Multiple stack-based buffer overflows in (1) xpmParseColors in parse.c, (2) ParseAndPutPixels in create.c, and (3) ParsePixels in parse.c for libXpm before 6.8.1 allow remote attackers to execute arbitrary code via a malformed XPM image file.
CVE-2008-4609 12 Bsd, Bsdi, Cisco and 9 more 22 Bsd, Bsd Os, Catalyst Blade Switch 3020 and 19 more 2022-12-14 7.1 HIGH 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-1999-0303 4 Digital, Netbsd, Openbsd and 1 more 5 Osf 1, Netbsd, Openbsd and 2 more 2022-08-17 4.6 MEDIUM N/A
Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames.
CVE-1999-0304 4 Bsdi, Freebsd, Netbsd and 1 more 4 Bsd Os, Freebsd, Netbsd and 1 more 2022-08-17 7.2 HIGH N/A
mmap function in BSD allows local attackers in the kmem group to modify memory through devices.
CVE-1999-0396 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2022-08-17 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-1999-0061 4 Bsdi, Freebsd, Linux and 1 more 4 Bsd Os, Freebsd, Linux Kernel and 1 more 2022-08-17 5.1 MEDIUM N/A
File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).
CVE-2022-27882 1 Openbsd 1 Openbsd 2022-05-12 5.0 MEDIUM 7.5 HIGH
slaacd in OpenBSD 6.9 and 7.0 before 2022-03-22 has an integer signedness error and resultant heap-based buffer overflow triggerable by a crafted IPv6 router advertisement. NOTE: privilege separation and pledge can prevent exploitation.
CVE-2022-27881 1 Openbsd 1 Openbsd 2022-05-12 5.0 MEDIUM 7.5 HIGH
engine.c in slaacd in OpenBSD 6.9 and 7.0 before 2022-02-21 has a buffer overflow triggerable by an IPv6 router advertisement with more than seven nameservers. NOTE: privilege separation and pledge can prevent exploitation.
