CVE-1999-0396 | 2 Netbsd, Openbsd | 2 Netbsd, Openbsd | 2025-04-03 | 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-1999-0323 | 4 Bsdi, Freebsd, Netbsd and 1 more | 4 Bsd Os, Freebsd, Netbsd and 1 more | 2025-04-03 | N/A |
FreeBSD mmap function allows users to modify append-only or immutable files. | ||||
CVE-1999-1214 | 5 Bsd, Freebsd, Netbsd and 2 more | 5 Bsd, Freebsd, Netbsd and 2 more | 2025-04-03 | N/A |
The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID. | ||||
CVE-2000-0750 | 3 Netbsd, Openbsd, Redhat | 3 Netbsd, Openbsd, Linux | 2025-04-03 | N/A |
Buffer overflow in mopd (Maintenance Operations Protocol loader daemon) allows remote attackers to execute arbitrary commands via a long file name. | ||||
CVE-2000-0995 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
Format string vulnerability in OpenBSD yp_passwd program (and possibly other BSD-based operating systems) allows attackers to gain root privileges a malformed name. | ||||
CVE-2001-0053 | 3 David Madore, Netbsd, Openbsd | 3 Ftpd-bsd, Netbsd, Openbsd | 2025-04-03 | N/A |
One-byte buffer overflow in replydirname function in BSD-based ftpd allows remote attackers to gain root privileges. | ||||
CVE-2001-0284 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header (AH) IPv4 option. | ||||
CVE-2001-1559 | 1 Openbsd | 1 Openbsd | 2025-04-03 | 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-2002-0557 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
Vulnerability in OpenBSD 3.0, when using YP with netgroups in the password database, causes (1) rexec or (2) rsh to run another user's shell, or (3) atrun to change to a different user's directory, possibly due to memory allocation failures or an incorrect call to auth_approval(). | ||||
CVE-2002-1915 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | 5.5 Medium |
tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file. | ||||
CVE-2002-2280 | 1 Openbsd | 1 Openbsd | 2025-04-03 | N/A |
syslogd on OpenBSD 2.9 through 3.2 does not change the source IP address of syslog packets when the machine's IP addressed is changed without rebooting, e.g. via ifconfig, which can cause incorrect information to be sent to the syslog server. | ||||
CVE-2025-30334 | 1 Openbsd | 1 Openbsd | 2025-03-21 | 6.5 Medium |
In OpenBSD 7.6 before errata 006 and OpenBSD 7.5 before errata 015, traffic sent over wg(4) could result in kernel crash. | ||||
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-2024-11148 | 1 Openbsd | 1 Openbsd | 2024-12-06 | 7.5 High |
In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request. | ||||
CVE-2024-10933 | 1 Openbsd | 1 Openbsd | 2024-12-05 | 5 Medium |
In OpenBSD 7.5 before errata 009 and OpenBSD 7.4 before errata 022, exclude any '/' in readdir name validation to avoid unexpected directory traversal on untrusted file systems. | ||||
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. |
