|---|---|---|---|---|
| CVE-2015-5600 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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-2015-6563 | 3 Apple, Openbsd, Redhat | 3 Mac Os X, Openssh, Enterprise Linux | 2025-04-12 | 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-2016-0778 | 6 Apple, Hp, Openbsd and 3 more | 7 Mac Os X, Virtual Customer Access System, Openssh and 4 more | 2025-04-12 | N/A |
| 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-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | 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-2016-0777 | 6 Apple, Hp, Openbsd and 3 more | 8 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 5 more | 2025-04-12 | N/A |
| 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-2016-10012 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| 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-2015-5352 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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 | 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-2016-3115 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Vm Server, Enterprise Linux | 2025-04-12 | N/A |
| 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-2013-2125 | 1 Openbsd | 1 Opensmtpd | 2025-04-12 | 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-2016-1907 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| 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-2014-7250 | 4 Bsd, Freebsd, Netbsd and 1 more | 4 Bsd, Freebsd, Netbsd and 1 more | 2025-04-12 | 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-2014-2653 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| The verify_host_key function in sshconnect.c in the client in OpenSSH 6.6 and earlier allows remote servers to trigger the skipping of SSHFP DNS RR checking by presenting an unacceptable HostCertificate. | ||||
| CVE-2016-10011 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| 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-2010-4754 | 4 Apple, Freebsd, Netbsd and 1 more | 4 Mac Os X, Freebsd, Netbsd and 1 more | 2025-04-11 | N/A |
| The glob implementation in libc in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, and OpenBSD 4.7, and Libsystem in Apple Mac OS X before 10.6.8, allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632. | ||||
| CVE-2010-4478 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| OpenSSH 5.6 and earlier, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol, a related issue to CVE-2010-4252. | ||||
| CVE-2011-4327 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| ssh-keysign.c in ssh-keysign in OpenSSH before 5.8p2 on certain platforms executes ssh-rand-helper with unintended open file descriptors, which allows local users to obtain sensitive key information via the ptrace system call. | ||||
| CVE-2011-5000 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-11 | N/A |
| The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field. NOTE: there may be limited scenarios in which this issue is relevant. | ||||
| CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. | ||||
| CVE-2011-0539 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks. | ||||
