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-2016-6241 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 7.2 HIGH | 7.8 HIGH |
Integer overflow in the amap_alloc1 function in OpenBSD 5.8 and 5.9 allows local users to execute arbitrary code with kernel privileges via a large size value. | |||||
CVE-2016-6239 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 4.9 MEDIUM | 5.5 MEDIUM |
The mmap extension __MAP_NOFAULT in OpenBSD 5.8 and 5.9 allows attackers to cause a denial of service (kernel panic and crash) via a large size value. | |||||
CVE-2016-6210 | 1 Openbsd | 1 Openssh | 2025-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | |||||
CVE-2017-1000373 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 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-2016-6244 | 1 Openbsd | 1 Openbsd | 2025-04-20 | 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. | |||||
CVE-2015-7687 | 2 Fedoraproject, Openbsd | 2 Fedora, Opensmtpd | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
Use-after-free vulnerability in OpenSMTPD before 5.7.2 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via vectors involving req_ca_vrfy_smtp and req_ca_vrfy_mta. | |||||
CVE-2016-3115 | 2 Openbsd, Oracle | 2 Openssh, Vm Server | 2025-04-12 | 5.5 MEDIUM | 6.4 MEDIUM |
Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH before 7.2p2 allow remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions. | |||||
CVE-2016-10012 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.2 HIGH | 7.8 HIGH |
The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | |||||
CVE-2014-7250 | 4 Bsd, Freebsd, Netbsd and 1 more | 4 Bsd, Freebsd, Netbsd and 1 more | 2025-04-12 | 5.0 MEDIUM | N/A |
The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets. | |||||
CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.8 HIGH | 7.5 HIGH |
** DISPUTED ** 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-2015-5352 | 1 Openbsd | 1 Openssh | 2025-04-12 | 4.3 MEDIUM | N/A |
The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window. | |||||
CVE-2014-9424 | 1 Openbsd | 1 Libressl | 2025-04-12 | 7.5 HIGH | N/A |
Double free vulnerability in the ssl_parse_clienthello_use_srtp_ext function in d1_srtp.c in LibreSSL before 2.1.2 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a certain length-verification error during processing of a DTLS handshake. | |||||
CVE-2014-9278 | 2 Openbsd, Redhat | 3 Openssh, Enterprise Linux, Fedora | 2025-04-12 | 4.0 MEDIUM | N/A |
The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login. | |||||
CVE-2013-2125 | 1 Openbsd | 1 Opensmtpd | 2025-04-12 | 5.0 MEDIUM | N/A |
OpenSMTPD before 5.3.2 does not properly handle SSL sessions, which allows remote attackers to cause a denial of service (connection blocking) by keeping a connection open. | |||||
CVE-2016-10010 | 1 Openbsd | 1 Openssh | 2025-04-12 | 6.9 MEDIUM | 7.0 HIGH |
sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c. | |||||
CVE-2015-5600 | 1 Openbsd | 1 Openssh | 2025-04-12 | 8.5 HIGH | N/A |
The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list. | |||||
CVE-2016-6515 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2025-04-12 | 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-2014-2532 | 2 Openbsd, Oracle | 2 Openssh, Communications User Data Repository | 2025-04-12 | 5.8 MEDIUM | 4.9 MEDIUM |
sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character. | |||||
CVE-2016-0777 | 5 Apple, Hp, Openbsd and 2 more | 7 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 4 more | 2025-04-12 | 4.0 MEDIUM | 6.5 MEDIUM |
The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key. |
