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-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-2015-6565 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-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-2015-6563 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-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-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-2014-9278 2 Openbsd, Redhat 3 Openssh, Enterprise Linux, Fedora 2025-04-12 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-2013-4548 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-2012-0814 1 Openbsd 1 Openssh 2025-04-11 N/A
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.
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-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-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-2011-5000 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-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-2010-5107 2 Openbsd, Redhat 2 Openssh, Enterprise Linux 2025-04-11 N/A
The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections.
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.
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-2011-1013 3 Linux, Openbsd, Redhat 4 Linux Kernel, Openbsd, Enterprise Linux and 1 more 2025-04-11 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-2011-2168 1 Openbsd 1 Openbsd 2025-04-11 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.
