The (1) ssh2_load_userkey and (2) ssh2_save_userkey functions in PuTTY 0.51 through 0.63 do not properly wipe SSH-2 private keys from memory, which allows local users to obtain sensitive information by reading the memory. Las funciones (1) ssh2_load_userkey y (2) ssh2_save_userkey en PuTTY 0.51 hasta 0.63 no limpian correctamente las claves privadas SSH-2 de la memoria, lo que permite a usuarios remotos obtener información sensible mediante la lectura de la memoria. • http://lists.fedoraproject.org/pipermail/package-announce/2015-March/151790.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/151839.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/151933.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00032.html http://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/private-key-not-wiped-2.html http://www.debian.org/security/2015/dsa& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

PuTTY 0.59 through 0.61 does not clear sensitive process memory when managing user replies that occur during keyboard-interactive authentication, which might allow local users to read login passwords by obtaining access to the process' memory. PuTTY v0.59 hasta v0.61 no borra la memoria de procesos sensibles en la gestión de las respuestas del usuario que se producen durante la autenticación interactiva por teclado, lo que podría permitir a usuarios locales leer las contraseñas de inicio de sesión mediante la obtención de acceso a la memoria del proceso. • http://seclists.org/oss-sec/2011/q4/499 http://seclists.org/oss-sec/2011/q4/500 http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/password-not-wiped.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The rsa_verify function in PuTTY before 0.63 (1) does not clear sensitive process memory after use and (2) does not free certain structures containing sensitive process memory, which might allow local users to discover private RSA and DSA keys. La función rsa_verify en PuTTY anterior a 0.63 (1) no limpia de memoria los procesos sensibles después de usarlos y (2)no libera determinadas estructuras que contienen procesos sensibles, lo que podría permitir a usuarios locales descubrir claves privadas RSA y DSA. • http://lists.opensuse.org/opensuse-updates/2013-08/msg00035.html http://secunia.com/advisories/54379 http://secunia.com/advisories/54533 http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/private-key-not-wiped.html http://www.debian.org/security/2013/dsa-2736 http://www.openwall.com/lists/oss-security/2013/08/06/11 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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 •
