CVE-2023-35784 1 Openbsd 2 Libressl, Openbsd 2023-11-06 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-2019-19726 1 Openbsd 1 Openbsd 2023-10-06 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-2023-38283 2 Openbgpd, Openbsd 2 Openbgpd, Openbsd 2023-09-07 5.3 Medium
In OpenBGPD before 8.1, incorrect handling of BGP update data (length of path attributes) set by a potentially distant remote actor may cause the system to incorrectly reset a session. This is fixed in OpenBSD 7.3 errata 006.
CVE-2023-40216 1 Openbsd 1 Openbsd 2023-08-23 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-2021-46880 1 Openbsd 2 Libressl, Openbsd 2023-05-17 9.8 Critical
x509/x509_verify.c in LibreSSL before 3.4.2, and OpenBSD before 7.0 errata 006, allows authentication bypass because an error for an unverified certificate chain is sometimes discarded.
CVE-2022-48437 1 Openbsd 2 Libressl, Openbsd 2023-04-21 5.3 Medium
An issue was discovered in x509/x509_verify.c in LibreSSL before 3.6.1, and in OpenBSD before 7.2 errata 001. x509_verify_ctx_add_chain does not store errors that occur during leaf certificate verification, and therefore an incorrect error is returned. This behavior occurs when there is an installed verification callback that instructs the verifier to continue upon detecting an invalid certificate.
CVE-2023-27567 1 Openbsd 1 Openbsd 2023-04-06 7.5 High
In OpenBSD 7.2, a TCP packet with destination port 0 that matches a pf divert-to rule can crash the kernel.
CVE-2019-14899 4 Apple, Freebsd, Linux and 1 more 8 Ipados, Iphone Os, Mac Os X and 5 more 2023-03-01 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 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-2004-0687 4 Openbsd, Suse, X.org and 1 more 4 Openbsd, Suse Linux, X11r6 and 1 more 2023-01-20 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 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-2009-3572 1 Openbsd 1 Openbsd 2022-10-03 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-2002-2180 1 Openbsd 1 Openbsd 2022-10-03 N/A
The setitimer(2) system call in OpenBSD 2.0 through 3.1 does not properly check certain arguments, which allows local users to write to kernel memory and possibly gain root privileges, possibly via an integer signedness error.
CVE-2002-2188 1 Openbsd 1 Openbsd 2022-10-03 N/A
OpenBSD before 3.2 allows local users to cause a denial of service (kernel crash) via a call to getrlimit(2) with invalid arguments, possibly due to an integer signedness error.
CVE-2006-5550 2 Freebsd, Openbsd 2 Freebsd, Openbsd 2022-10-03 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-2004-2338 1 Openbsd 1 Openbsd 2022-10-03 N/A
OpenBSD 3.3 and 3.4 does not properly parse Accept and Deny rules without netmasks on big-endian 64-bit platforms such as SPARC64, which may allow remote attackers to bypass access restrictions.
CVE-1999-0396 2 Netbsd, Openbsd 2 Netbsd, Openbsd 2022-08-17 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 2022-08-17 N/A
mmap function in BSD allows local attackers in the kmem group to modify memory through devices.
CVE-1999-0303 4 Digital, Netbsd, Openbsd and 1 more 5 Osf 1, Netbsd, Openbsd and 2 more 2022-08-17 N/A
Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames.
CVE-1999-0061 4 Bsdi, Freebsd, Linux and 1 more 4 Bsd Os, Freebsd, Linux Kernel and 1 more 2022-08-17 N/A
File creation and deletion, and remote execution, in the BSD line printer daemon (lpd).
