| CVE-2019-19726 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 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 | 7.8 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 | 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 | 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 | 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-2019-16905 | 3 Netapp, Openbsd, Siemens | 7 Cloud Backup, Steelstore Cloud Integrated Storage, Openssh and 4 more | 2024-11-21 | 7.8 High |
| OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. This leads to memory corruption and local code execution because of an error in the XMSS key parsing algorithm. NOTE: the XMSS implementation is considered experimental in all released OpenSSH versions, and there is no supported way to enable it when building portable OpenSSH. | ||||
| CVE-2019-14899 | 4 Apple, Freebsd, Linux and 1 more | 8 Ipados, Iphone Os, Mac Os X and 5 more | 2024-11-21 | 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-2018-8970 | 1 Openbsd | 1 Libressl | 2024-11-21 | N/A |
| The int_x509_param_set_hosts function in lib/libcrypto/x509/x509_vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. NOTE: the LibreSSL documentation indicates that this special case is supported, but the BoringSSL documentation does not. | ||||
| CVE-2018-20685 | 9 Canonical, Debian, Fujitsu and 6 more | 30 Ubuntu Linux, Debian Linux, M10-1 and 27 more | 2024-11-21 | 5.3 Medium |
| In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. | ||||
| CVE-2018-15919 | 2 Netapp, Openbsd | 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more | 2024-11-21 | N/A |
| Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' | ||||
| CVE-2018-15473 | 7 Canonical, Debian, Netapp and 4 more | 25 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 22 more | 2024-11-21 | 5.3 Medium |
| OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. | ||||
| CVE-2018-14775 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A |
| tss_alloc in sys/arch/i386/i386/gdt.c in OpenBSD 6.2 and 6.3 has a Local Denial of Service (system crash) due to incorrect I/O port access control on the i386 architecture. | ||||
| CVE-2018-12434 | 1 Openbsd | 1 Libressl | 2024-11-21 | N/A |
| LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | ||||
| CVE-2017-8301 | 1 Openbsd | 1 Libressl | 2024-11-21 | N/A |
| LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx. | ||||
| CVE-2017-5850 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A |
| httpd in OpenBSD allows remote attackers to cause a denial of service (memory consumption) via a series of requests for a large file using an HTTP Range header. | ||||
| CVE-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 23 Debian Linux, Active Iq Unified Manager, Cloud Backup and 20 more | 2024-11-21 | 5.3 Medium |
| The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. | ||||
| CVE-2017-1000373 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A |
| The OpenBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2017-1000372 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A |
| A flaw exists in OpenBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using setuid binaries such as /usr/bin/at. This affects OpenBSD 6.1 and possibly earlier versions. | ||||
| CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2024-11-21 | N/A |
| The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue." | ||||
| CVE-2016-6522 | 1 Openbsd | 1 Openbsd | 2024-11-21 | N/A |
| Integer overflow in the uvm_map_isavail function in uvm/uvm_map.c in OpenBSD 5.9 allows local users to cause a denial of service (kernel panic) via a crafted mmap call, which triggers the new mapping to overlap with an existing mapping. | ||||
