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 •

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 •

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". Vulnerabilidad distinta de CVE-2013-4206. • 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/vuln-bignum-division-by-zero.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 •

Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service (crash) and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the SSH handshake, which triggers a heap-based buffer overflow. Desbordamiento de entero en PuTTY 0.62 y anteriores, WinSCP anterior a 5.1.6, y otros productos que usan PuTTY, permite a servidores SSH remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario en determinadas aplicaciones que utilizan PuTTY a través de un tamaño negativo en el valor de la firma en la clave RSA durante el handshake SSH, que provoca un desbordamiento basado en memoria dinámica. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=718779 http://lists.opensuse.org/opensuse-updates/2013-08/msg00035.html http://lists.opensuse.org/opensuse-updates/2013-08/msg00041.html http://secunia.com/advisories/54379 http://secunia.com/advisories/54517 http://secunia.com/advisories/54533 http://svn.tartarus.org/sgt?view=revision&sortby=date&revision=9896 http://winscp.net/tracker/show_bug.cgi?id=1017 http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/vuln-signature&# • CWE-189: Numeric Errors •

PuTTY 0.59 and earlier uses weak file permissions for (1) ppk files containing private keys generated by puttygen and (2) session logs created by putty, which allows local users to gain sensitive information by reading these files. PuTTY 0.59 y versiones anteriores utiliza un fichero de permisos débil para (1) ficheros ppk que contienen las claves privadas generadas por el puttygen y (2) los logs de sesión creados por el putty, lo que permite a usuarios locales la obtención de información sensible mediante la lectura de estos ficheros. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400804 http://secunia.com/advisories/24381 •
