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. La función ssh_packet_read_poll2 en packet.c en OpenSSH en versiones anteriores a 7.1p2 permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango y caída de aplicación) a través de tráfico de red manipulado. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176516.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175676.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176349.html http://www.openssh.com/txt/release-7.1p2 http://www.securityfocus.com/bid/81293 https://anongit.mindrot.org/openssh.git/commit/?id=2fecfd486bdba9f51b3a789277bb0733ca36e1c0 https://bto.bluecoat.com/security-advisory/sa109 https://cert-portal.siemens.com/productcert/pd • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 6.5EPSS: 0%CPEs: 58EXPL: 0CVE-2016-0777 – OpenSSH: Client Information leak due to use of roaming connection feature
https://notcve.org/view.php?id=CVE-2016-0777
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. La función resend_bytes en roaming_common.c en el cliente en OpenSSH 5.x, 6.x y 7.x en versiones anteriores a 7.1p2 permite a servidores remotos obtener información sensible desde la memoria de proceso mediante la petición de transmisión de un buffer completo, según lo demostrado mediante la lectura de una clave privada. An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10734 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176516.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175592.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175676.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176349.html http://lists.opensuse.org/opensuse-security-announce • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-682: Incorrect Calculation •
CVSS: 8.1EPSS: 0%CPEs: 44EXPL: 1CVE-2016-0778 – OpenSSH: Client buffer-overflow when using roaming connections
https://notcve.org/view.php?id=CVE-2016-0778
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. Las funciones (1) roaming_read y (2) roaming_write en roaming_common.c en el cliente en OpenSSH 5.x, 6.x y 7.x en versiones anteriores a 7.1p2, cuando ciertas opciones proxy y forward se encuentran habilitadas, no mantiene adecuadamente los descriptores de archivo de conexión, lo que permite a servidores remotos causar una denegación de servicio (desbordamiento de buffer basado en memoria dinámica) o posiblemente tener otro impacto no especificado mediante la petición de varios reenvíos. A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10734 http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176516.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176349.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-01& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2015-6565
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. El fichero sshd en OpenSSH 6.8 and 6.9 fija permisos de lectura para cualquier usuario en dispositivos TTY, lo que posibilita a usuarios locales provocar denegación de servicio (desorganización de terminales) o tener un impacto inesperado al escribir sobre un dispositivo, como se demuestra escribiendo una secuencia de escape OpenSSH versions 6.8 and 6.9 suffer from a PTY privilege escalation vulnerability. • https://www.exploit-db.com/exploits/41173 http://openwall.com/lists/oss-security/2017/01/26/2 http://www.openssh.com/txt/release-7.0 http://www.openwall.com/lists/oss-security/2015/08/22/1 http://www.securityfocus.com/bid/76497 http://www.securitytracker.com/id/1033917 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05131085 https://h20566.www2.hpe.com/portal/site&# • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2015-6564
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. Vulnerabilidad de uso después de la liberación de la memoria en la función mm_answer_pam_free_ctx en monitor.c en sshd en OpenSSH en versiones anteriores a 7.0 en plataformas no OpenBSD, podría permitir a usuarios locales obtener privilegios mediante el aprovechamiento del control del sshd uid para enviar una petición MONITOR_REQ_PAM_FREE_CTX inesperadamente temprana. A use-after-free flaw was found in OpenSSH. An attacker able to fully compromise a non-privileged pre-authentication process using a different flaw could possibly cause sshd to crash or execute arbitrary code with root privileges. • http://lists.fedoraproject.org/pipermail/package-announce/2015-August/165170.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00017.html http://rhn.redhat.com/errata/RHSA-2016-0741.html http://seclists.org/fulldisclosure/2015/Aug/54 http://www.openssh.com/txt/release-7.0 http://www.openwall.com/lists/oss-security/2015/08/22/1 http://www.oracle.com/technetwork/topics/security/bulletinjan2016-2867206.html http://www.oracle.com/technetwork/topics/security/linuxbulletinapr20 • CWE-264: Permissions, Privileges, and Access Controls CWE-416: Use After Free •
