CVE-2016-10010 | 1 Openbsd | 1 Openssh | 2022-12-13 | 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-2016-1908 | 4 Debian, Openbsd, Oracle and 1 more | 9 Debian Linux, Openssh, Linux and 6 more | 2022-12-13 | 7.5 HIGH | 9.8 CRITICAL |
The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server. | |||||
CVE-2016-1907 | 1 Openbsd | 1 Openssh | 2022-12-13 | 5.0 MEDIUM | 5.3 MEDIUM |
The ssh_packet_read_poll2 function in packet.c in OpenSSH before 7.1p2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic. | |||||
CVE-2016-10009 | 1 Openbsd | 1 Openssh | 2022-12-13 | 7.5 HIGH | 7.3 HIGH |
Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket. | |||||
CVE-2016-8858 | 1 Openbsd | 1 Openssh | 2022-12-13 | 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-2015-6563 | 2 Apple, Openbsd | 2 Mac Os X, Openssh | 2022-12-13 | 1.9 LOW | N/A |
The monitor component in sshd in OpenSSH before 7.0 on non-OpenBSD platforms accepts extraneous username data in MONITOR_REQ_PAM_INIT_CTX requests, which allows local users to conduct impersonation attacks by leveraging any SSH login access in conjunction with control of the sshd uid to send a crafted MONITOR_REQ_PWNAM request, related to monitor.c and monitor_wrap.c. | |||||
CVE-2016-6515 | 2 Fedoraproject, Openbsd | 2 Fedora, Openssh | 2022-12-13 | 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-2017-15906 | 5 Debian, Netapp, Openbsd and 2 more | 22 Debian Linux, Active Iq Unified Manager, Cloud Backup and 19 more | 2022-12-13 | 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-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2022-12-13 | 4.6 MEDIUM | 8.1 HIGH |
The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. | |||||
CVE-2015-5600 | 1 Openbsd | 1 Openssh | 2022-12-13 | 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-2016-0777 | 5 Apple, Hp, Openbsd and 2 more | 7 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 4 more | 2022-12-13 | 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. | |||||
CVE-2019-6111 | 5 Canonical, Debian, Openbsd and 2 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2022-12-13 | 5.8 MEDIUM | 5.9 MEDIUM |
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). | |||||
CVE-2015-5352 | 1 Openbsd | 1 Openssh | 2022-12-13 | 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-2003-1562 | 1 Openbsd | 1 Openssh | 2022-12-13 | 7.6 HIGH | N/A |
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190. | |||||
CVE-2016-10011 | 1 Openbsd | 1 Openssh | 2022-12-13 | 2.1 LOW | 5.5 MEDIUM |
authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process. | |||||
CVE-2016-6210 | 1 Openbsd | 1 Openssh | 2022-12-13 | 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-2015-6564 | 1 Openbsd | 1 Openssh | 2022-12-13 | 6.9 MEDIUM | N/A |
Use-after-free vulnerability in the mm_answer_pam_free_ctx function in monitor.c in sshd in OpenSSH before 7.0 on non-OpenBSD platforms might allow local users to gain privileges by leveraging control of the sshd uid to send an unexpectedly early MONITOR_REQ_PAM_FREE_CTX request. | |||||
CVE-2011-0419 | 9 Apache, Apple, Debian and 6 more | 10 Http Server, Portable Runtime, Mac Os X and 7 more | 2022-09-19 | 4.3 MEDIUM | N/A |
Stack consumption vulnerability in the fnmatch implementation in apr_fnmatch.c in the Apache Portable Runtime (APR) library before 1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle Solaris 10, and Android, allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via *? sequences in the first argument, as demonstrated by attacks against mod_autoindex in httpd. | |||||
CVE-2000-0143 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2022-08-17 | 4.6 MEDIUM | N/A |
The SSH protocol server sshd allows local users without shell access to redirect a TCP connection through a service that uses the standard system password database for authentication, such as POP or FTP. | |||||
CVE-1999-0303 | 4 Digital, Netbsd, Openbsd and 1 more | 5 Osf 1, Netbsd, Openbsd and 2 more | 2022-08-17 | 4.6 MEDIUM | N/A |
Buffer overflow in BNU UUCP daemon (uucpd) through long hostnames. |
