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-2002-0391 | 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-2002-0414 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | N/A |
KAME-derived implementations of IPsec on NetBSD 1.5.2, FreeBSD 4.5, and other operating systems, does not properly consult the Security Policy Database (SPD), which could cause a Security Gateway (SG) that does not use Encapsulating Security Payload (ESP) to forward forged IPv4 packets. | ||||
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-2002-1221 | 3 Freebsd, Isc, Openbsd | 3 Freebsd, Bind, Openbsd | 2025-04-03 | N/A |
BIND 8.x through 8.3.3 allows remote attackers to cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference. | ||||
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-2003-0028 | 11 Cray, Freebsd, Gnu and 8 more | 15 Unicos, Freebsd, Glibc and 12 more | 2025-04-03 | N/A |
Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391. | ||||
CVE-2003-0386 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-03 | N/A |
OpenSSH 3.6.1 and earlier, when restricting host access by numeric IP addresses and with VerifyReverseMapping disabled, allows remote attackers to bypass "from=" and "user@host" address restrictions by connecting to a host from a system whose reverse DNS hostname contains the numeric IP address. | ||||
CVE-2003-0466 | 7 Apple, Freebsd, Netbsd and 4 more | 10 Mac Os X, Mac Os X Server, Freebsd and 7 more | 2025-04-03 | 9.8 Critical |
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO. | ||||
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-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-2023-51767 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2024-11-21 | 7.0 High |
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. |
