CVE-2004-0219 1 Openbsd 1 Openbsd 2025-04-03 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-2004-0687 5 Openbsd, Redhat, Suse and 2 more 6 Openbsd, Enterprise Linux, Network Satellite and 3 more 2025-04-03 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-2004-0819 1 Openbsd 1 Openbsd 2025-04-03 N/A
The bridge functionality in OpenBSD 3.4 and 3.5, when running a gateway configured as a bridging firewall with the link2 option for IPSec enabled, allows remote attackers to cause a denial of service (crash) via an ICMP echo (ping) packet.
CVE-2004-2230 1 Openbsd 1 Openbsd 2025-04-03 N/A
Heap-based buffer overflow in isakmpd on OpenBSD 3.4 through 3.6 allows local users to cause a denial of service (panic) and corrupt memory via IPSEC credentials on a socket.
CVE-2002-0391 5 Freebsd, Microsoft, Openbsd and 2 more 9 Freebsd, Windows 2000, Windows Nt and 6 more 2025-04-03 9.8 Critical
Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
CVE-2023-27567 1 Openbsd 1 Openbsd 2025-03-06 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-2022-48437 1 Openbsd 2 Libressl, Openbsd 2025-02-10 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-2021-46880 1 Openbsd 2 Libressl, Openbsd 2025-02-07 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-2023-35784 1 Openbsd 2 Libressl, Openbsd 2024-12-17 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-2023-52558 1 Openbsd 1 Openbsd 2024-11-21 7.5 High
In OpenBSD 7.4 before errata 002 and OpenBSD 7.3 before errata 019, a network buffer that had to be split at certain length that could crash the kernel after receiving specially crafted escape sequences.
CVE-2023-52556 1 Openbsd 1 Openbsd 2024-11-21 6.2 Medium
In OpenBSD 7.4 before errata 009, a race condition between pf(4)'s processing of packets and expiration of packet states may cause a kernel panic.
CVE-2023-51384 2 Debian, Openbsd 2 Debian Linux, Openssh 2024-11-21 5.5 Medium
In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys.
CVE-2023-40216 1 Openbsd 1 Openbsd 2024-11-21 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-2023-38408 3 Fedoraproject, Openbsd, Redhat 9 Fedora, Openssh, Devworkspace and 6 more 2024-11-21 9.8 Critical
The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009.
CVE-2023-38283 3 Bgp, Openbgpd, Openbsd 3 Openbgpd, Openbgpd, Openbsd 2024-11-21 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-2023-29323 2 Openbsd, Opensmtpd 2 Openbsd, Opensmtpd 2024-11-21 7.8 High
ascii_load_sockaddr in smtpd in OpenBSD before 7.1 errata 024 and 7.2 before errata 020, and OpenSMTPD Portable before 7.0.0-portable commit f748277, can abort upon a connection from a local, scoped IPv6 address.
CVE-2023-28531 2 Netapp, Openbsd 4 Brocade Fabric Operating System, Hci Bootstrap Os, Solidfire Element Os and 1 more 2024-11-21 9.8 Critical
ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9.
CVE-2023-25136 4 Fedoraproject, Netapp, Openbsd and 1 more 10 Fedora, 500f, 500f Firmware and 7 more 2024-11-21 6.5 Medium
OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states "remote code execution is theoretically possible."
CVE-2022-27882 1 Openbsd 1 Openbsd 2024-11-21 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 2024-11-21 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.
