|---|---|---|---|---|
| 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-2016-10012 | 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-2016-10009 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | N/A |
| 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-2016-1907 | 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-2016-10010 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| 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-2015-5352 | 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-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-2015-6565 | 1 Openbsd | 1 Openssh | 2025-04-12 | N/A |
| sshd in OpenSSH 6.8 and 6.9 uses world-writable permissions for TTY devices, which allows local users to cause a denial of service (terminal disruption) or possibly have unspecified other impact by writing to a device, as demonstrated by writing an escape sequence. | ||||
| 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-2016-6515 | 3 Fedoraproject, Openbsd, Redhat | 3 Fedora, Openssh, Enterprise Linux | 2025-04-12 | N/A |
| 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-2014-9424 | 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-2015-6564 | 2 Openbsd, Redhat | 2 Openssh, Enterprise Linux | 2025-04-12 | 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-2014-2532 | 3 Openbsd, Oracle, Redhat | 3 Openssh, Communications User Data Repository, Enterprise Linux | 2025-04-12 | N/A |
| 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-2016-8858 | 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-2014-1692 | 1 Openbsd | 1 Openssh | 2025-04-11 | N/A |
| The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. | ||||
| CVE-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | N/A |
| The (1) remote_glob function in sftp-glob.c and the (2) process_put function in sftp.c in OpenSSH 5.8 and earlier, as used in FreeBSD 7.3 and 8.1, NetBSD 5.0.2, OpenBSD 4.7, and other products, allow 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 SSH_FXP_STAT requests to an sftp daemon, a different vulnerability than CVE-2010-2632. | ||||
| CVE-2011-0419 | 10 Apache, Apple, Debian and 7 more | 12 Http Server, Portable Runtime, Mac Os X and 9 more | 2025-04-11 | 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-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-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. | ||||
