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

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.
