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-2004-0079 | 23 4d, Apple, Avaya and 20 more | 66 Webstar, Mac Os X, Mac Os X Server and 63 more | 2025-01-16 | 5.0 MEDIUM | 7.5 HIGH |
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | |||||
CVE-2002-0391 | 4 Freebsd, Microsoft, Openbsd and 1 more | 7 Freebsd, Windows 2000, Windows Nt and 4 more | 2025-01-16 | 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-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. | |||||
CVE-2020-16088 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. | |||||
CVE-2019-8460 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service. | |||||
CVE-2019-6724 | 4 Apple, Barracuda, Linux and 1 more | 4 Mac Os X, Vpn Client, Linux Kernel and 1 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
The barracudavpn component of the Barracuda VPN Client prior to version 5.0.2.7 for Linux, macOS, and OpenBSD runs as a privileged process and can allow an unprivileged local attacker to load a malicious library, resulting in arbitrary code executing as root. | |||||
CVE-2019-19726 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root. | |||||
CVE-2019-19522 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root. | |||||
CVE-2019-19521 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
libc in OpenBSD 6.6 allows authentication bypass via the -schallenge username, as demonstrated by smtpd, ldapd, or radiusd. This is related to gen/auth_subr.c and gen/authenticate.c in libc (and login/login.c and xenocara/app/xenodm/greeter/verify.c). | |||||
CVE-2019-19520 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
xlock in OpenBSD 6.6 allows local users to gain the privileges of the auth group by providing a LIBGL_DRIVERS_PATH environment variable, because xenocara/lib/mesa/src/loader/loader.c mishandles dlopen. | |||||
CVE-2019-19519 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
In OpenBSD 6.6, local users can use the su -L option to achieve any login class (often excluding root) because there is a logic error in the main function in su/su.c. | |||||
CVE-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2024-11-21 | 4.9 MEDIUM | 7.4 HIGH |
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. |
