|---|---|---|---|---|---|
| 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-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-2016-10009 | 1 Openbsd | 1 Openssh | 2025-04-12 | 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-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2025-04-12 | 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-2015-5352 | 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-2015-6564 | 1 Openbsd | 1 Openssh | 2025-04-12 | 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-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-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-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-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-2016-8858 | 1 Openbsd | 1 Openssh | 2025-04-12 | 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-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-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. | |||||
| 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-2015-6565 | 1 Openbsd | 1 Openssh | 2025-04-12 | 7.2 HIGH | 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-2015-6563 | 2 Apple, Openbsd | 2 Mac Os X, Openssh | 2025-04-12 | 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-2011-1013 | 2 Linux, Openbsd | 2 Linux Kernel, Openbsd | 2025-04-11 | 7.2 HIGH | N/A |
| Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument. | |||||
| CVE-2010-4755 | 3 Freebsd, Netbsd, Openbsd | 4 Freebsd, Netbsd, Openbsd and 1 more | 2025-04-11 | 4.0 MEDIUM | 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-2011-2168 | 1 Openbsd | 1 Openbsd | 2025-04-11 | 5.0 MEDIUM | N/A |
| Multiple integer overflows in the glob implementation in libc in OpenBSD before 4.9 might allow context-dependent attackers to have an unspecified impact via a crafted string, related to the GLOB_APPEND and GLOB_DOOFFS flags, a different issue than CVE-2011-0418. | |||||
