A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification. Puede ocurrir una sobrescritura de memoria desencadenable remotamente en el intercambio de claves RSA en PuTTY, en versiones anteriores a la 0.71, antes de la verificación de claves del host. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00020.html https://lists.debian.org/debian-lts-announce/2019/04/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36LWQ3NPFIV7DC7TC4KFPRYRH2OR7SZ2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LDO3F267P347E6U2IILFCYW7JPTLCCES https://seclists.org/bugtraq/2019/Apr/6 https://security. • CWE-320: Key Management Errors •
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-2016-6167
Multiple untrusted search path vulnerabilities in Putty beta 0.67 allow local users to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse (1) UxTheme.dll or (2) ntmarta.dll file in the current working directory. Varias vulnerabilidades de rutas de búsqueda no confiables en Putty beta 0.67 permiten a los usuarios locales ejecutar código arbitrario y realizar ataques de secuestro de DLL mediante un archivo troyano (1) UxTheme.dll o (2) ntmarta.dll en el directorio de trabajo actual.

Buffer overflow in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) via an invalid DSA signature that is not properly handled during computation of a modular inverse and triggers the overflow during a division by zero by the bignum functionality, a different vulnerability than CVE-2013-4206. Desbordamiento de búfer en PuTTY 0.62 y anteriores, permite a servidores SSH remotos provocar una denegación de servicio (caída) a través de una firma DSA no válida que no es manejada adecuadamente durante el cálculo de un inverso modular que provoca el desbordamiento durante una división entre cero por la funcionalidad "bignum".

Heap-based buffer underflow in the modmul function in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) and possibly trigger memory corruption or code execution via a crafted DSA signature, which is not properly handled when performing certain bit-shifting operations during modular multiplication. Desbordamiento de búfer basado en memoria dinámica en la función modmul en sshbn.c en PuTTY 0.62 y anteriores, permite a servidores SSH remotos provocar una denegación de servicio (caída) y posiblemente causar una corrupción de memoria o ejecución de código a través de una firma DSA manipulada que no es manejada adecuadamente cuando se realizan determinadas operaciones de bit-shifting durante una multiplicación modular. • http://lists.opensuse.org/opensuse-updates/2013-08/msg00035.html http://secunia.com/advisories/54379 http://secunia.com/advisories/54533 http://svn.tartarus.org/sgt/putty/sshbn.c?sortby=date&r1=9977&r2=9976&pathrev=9977 http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-modmul.html http://www.debian.org/security/2013/dsa-2736 http://www.openwall.com/lists/oss-security/2013/08/06/11 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
