| CVE-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2024-08-05 | 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. | ||||
| CVE-2019-8460 | 1 Openbsd | 1 Openbsd | 2024-08-04 | 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 | 2024-08-04 | N/A |
| 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-2020-26142 | 1 Openbsd | 1 Openbsd | 2024-08-04 | 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 | 2024-08-04 | 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-2021-46880 | 1 Openbsd | 2 Libressl, Openbsd | 2024-08-04 | 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-2022-48437 | 1 Openbsd | 2 Libressl, Openbsd | 2024-08-03 | 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-2022-27882 | 1 Openbsd | 1 Openbsd | 2024-08-03 | 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 | 2024-08-03 | 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-2023-40216 | 1 Openbsd | 1 Openbsd | 2024-08-02 | 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 | 2024-08-02 | 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 | 2024-08-02 | 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 | 2024-08-02 | 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-2023-27567 | 1 Openbsd | 1 Openbsd | 2024-08-02 | 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-1999-0052 | 3 Bsdi, Freebsd, Openbsd | 3 Bsd Os, Freebsd, Openbsd | 2024-08-01 | 7.5 High |
| IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash. | ||||
| CVE-1999-1225 | 5 Digital, Linux, Netbsd and 2 more | 5 Ultrix, Linux Kernel, Netbsd and 2 more | 2024-08-01 | N/A |
| rpc.mountd on Linux, Ultrix, and possibly other operating systems, allows remote attackers to determine the existence of a file on the server by attempting to mount that file, which generates different error messages depending on whether the file exists or not. | ||||
| CVE-1999-1214 | 5 Bsd, Freebsd, Netbsd and 2 more | 5 Bsd, Freebsd, Netbsd and 2 more | 2024-08-01 | 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-1999-0798 | 5 Bsdi, Freebsd, Openbsd and 2 more | 7 Bsd Os, Freebsd, Openbsd and 4 more | 2024-08-01 | N/A |
| Buffer overflow in bootpd on OpenBSD, FreeBSD, and Linux systems via a malformed header type. | ||||
| CVE-1999-0703 | 3 Bsdi, Freebsd, Openbsd | 3 Bsd Os, Freebsd, Openbsd | 2024-08-01 | N/A |
| OpenBSD, BSDI, and other Unix operating systems allow users to set chflags and fchflags on character and block devices. | ||||
| CVE-1999-0727 | 1 Openbsd | 1 Openbsd | 2024-08-01 | N/A |
| A kernel leak in the OpenBSD kernel allows IPsec packets to be sent unencrypted. | ||||
