CVSS: 9.8EPSS: 40%CPEs: 3EXPL: 1CVE-2017-6542 – PuTTY < 0.68 - 'ssh_agent_channel_data' Integer Overflow Heap Corruption
https://notcve.org/view.php?id=CVE-2017-6542
The ssh_agent_channel_data function in PuTTY before 0.68 allows remote attackers to have unspecified impact via a large length value in an agent protocol message and leveraging the ability to connect to the Unix-domain socket representing the forwarded agent connection, which trigger a buffer overflow. La función ssh_agent_channel_data en PuTTY en versiones anteriores a 0.68 permite a atacantes remotos tener un impacto no especificado a través de un valor de longitud grande en un mensaje de protocolo de agente y aprovechando la capacidad para conectarse al socket de Unix-domain que representa la conexión de agente reenviada, lo que desencadena un desbordamiento de búfer. PuTTY versions prior to 0.68 suffer from an ssh_agent_channel_data integer overflow heap corruption vulnerability. • https://www.exploit-db.com/exploits/42137 http://lists.opensuse.org/opensuse-updates/2017-03/msg00055.html http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-agent-fwd-overflow.html http://www.securityfocus.com/bid/97156 http://www.securitytracker.com/id/1038067 https://git.tartarus.org/?p=simon/putty.git%3Ba=commitdiff%3Bh=4ff22863d895cb7ebfced4cf923a012a614adaa8 https://security.gentoo.org/glsa/201703-03 https://security.gentoo.org/glsa/201706-09 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2016-2563
Stack-based buffer overflow in the SCP command-line utility in PuTTY before 0.67 and KiTTY 0.66.6.3 and earlier allows remote servers to cause a denial of service (stack memory corruption) or execute arbitrary code via a crafted SCP-SINK file-size response to an SCP download request. Desbordamiento de buffer basado en pila en la utilidad comando-línea de SCP en PuTTY en versiones anteriores a 0.67 y KiTTY 0.66.6.3 y versiones anteriores permite a servidores remotos causar una denegación de servicio (corrupción de memoria de pila) o ejecutar código arbitrario a través de una respuesta de tamño de archivo SCP-SINK a una petición de descarga SCP. • https://www.exploit-db.com/exploits/39551 http://lists.opensuse.org/opensuse-updates/2016-05/msg00131.html http://seclists.org/fulldisclosure/2016/Mar/22 http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-pscp-sink-sscanf.html http://www.securityfocus.com/bid/84296 http://www.securitytracker.com/id/1035257 https://github.com/tintinweb/pub/tree/master/pocs/cve-2016-2563 https://security.gentoo.org/glsa/201606-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Integer overflow in the terminal emulator in PuTTY before 0.66 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via an ECH (erase characters) escape sequence with a large parameter value, which triggers a buffer underflow. Desbordamiento de entero en el emulador de terminal en PuTTY en versiones anteriores a 0.66 permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente ejecutar código arbitrario a través de una secuencia de escape ECH (borrar caracteres) con un valor de parámetro grande, que desencadena un desbordamiento inferior de buffer. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173021.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/173094.html http://lists.opensuse.org/opensuse-updates/2015-11/msg00099.html http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-ech-overflow.html http://www.debian.org/security/2015/dsa-3409 http://www.securitytracker.com/id/1034308 https://security.gentoo.org/glsa/201606-01 • CWE-189: Numeric Errors •
