|---|---|---|---|---|---|
| CVE-2002-1220 | 3 Freebsd, Isc, Openbsd | 3 Freebsd, Bind, Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size. | |||||
| CVE-2006-4435 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 4.9 MEDIUM | N/A |
| OpenBSD 3.8, 3.9, and possibly earlier versions allows context-dependent attackers to cause a denial of service (kernel panic) by allocating more semaphores than the default. | |||||
| CVE-2006-4304 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | 10.0 HIGH | N/A |
| Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver. | |||||
| CVE-2001-1559 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 2.1 LOW | 5.5 MEDIUM |
| The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference. | |||||
| CVE-1999-0482 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| OpenBSD kernel crash through TSS handling, as caused by the crashme program. | |||||
| CVE-2002-0391 | 4 Freebsd, Microsoft, Openbsd and 1 more | 7 Freebsd, Windows 2000, Windows Nt and 4 more | 2025-04-03 | 10.0 HIGH | 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-2004-2230 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 2.1 LOW | 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-2000-0962 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | 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-1999-0727 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted. | |||||
| CVE-2001-0247 | 5 Freebsd, Mit, Netbsd and 2 more | 5 Freebsd, Kerberos 5, Netbsd and 2 more | 2025-04-03 | 10.0 HIGH | N/A |
| Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. | |||||
| CVE-2023-27567 | 1 Openbsd | 1 Openbsd | 2025-03-06 | N/A | 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 | N/A | 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 | N/A | 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-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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-2023-38283 | 2 Openbgpd, Openbsd | 2 Openbgpd, Openbsd | 2024-11-21 | N/A | 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-2023-35784 | 1 Openbsd | 2 Libressl, Openbsd | 2024-11-21 | 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-2023-29323 | 2 Openbsd, Opensmtpd | 2 Openbsd, Opensmtpd | 2024-11-21 | N/A | 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-2022-27882 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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 | 2024-11-21 | 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. | |||||
| CVE-2020-26142 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 2.6 LOW | 5.3 MEDIUM |
| An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. | |||||
