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. | |||||
CVE-2018-8970 | 1 Openbsd | 1 Libressl | 2024-11-21 | 5.8 MEDIUM | 7.4 HIGH |
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 | 2.6 LOW | 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 | 5.0 MEDIUM | 5.3 MEDIUM |
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 | 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more | 2024-11-21 | 5.0 MEDIUM | 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 | 4.9 MEDIUM | 5.5 MEDIUM |
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 | 1.9 LOW | 4.7 MEDIUM |
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 | 2.6 LOW | 5.3 MEDIUM |
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 | 7.8 HIGH | 7.5 HIGH |
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 | 22 Debian Linux, Active Iq Unified Manager, Cloud Backup and 19 more | 2024-11-21 | 5.0 MEDIUM | 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 | 6.4 MEDIUM | 6.5 MEDIUM |
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 | 7.5 HIGH | 9.8 CRITICAL |
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 | 7.8 HIGH | 7.5 HIGH |
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 | 4.9 MEDIUM | 5.5 MEDIUM |
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. | |||||
CVE-2016-6515 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
The auth_password function in auth-passwd.c in sshd in OpenSSH before 7.3 does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service (crypt CPU consumption) via a long string. | |||||
CVE-2016-6350 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (NULL pointer dereference and panic) via a sysctl call with a path starting with 10,9. | |||||
CVE-2016-6247 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
OpenBSD 5.8 and 5.9 allows certain local users to cause a denial of service (kernel panic) by unmounting a filesystem with an open vnode on the mnt_vnodelist. | |||||
CVE-2016-6246 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.9 MEDIUM | 4.4 MEDIUM |
OpenBSD 5.8 and 5.9 allows certain local users with kern.usermount privileges to cause a denial of service (kernel panic) by mounting a tmpfs with a VNOVAL in the (1) username, (2) groupname, or (3) device name of the root node. | |||||
CVE-2016-6245 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
OpenBSD 5.8 and 5.9 allows local users to cause a denial of service (kernel panic) via a large size in a getdents system call. | |||||
CVE-2016-6244 | 1 Openbsd | 1 Openbsd | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
The sys_thrsigdivert function in kern/kern_sig.c in the OpenBSD kernel 5.9 allows remote attackers to cause a denial of service (panic) via a negative "ts.tv_sec" value. |
