In PuTTY versions before 0.71 on Windows, local attackers could hijack the application by putting a malicious help file in the same directory as the executable. En PuTTY, en versiones anteriores a la 0.71 en Windows, los atacantes locales podrían secuestrar la aplicación colocando un archivo de ayuda malicioso en el mismo directorio que el ejecutable. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00020.html https://security.netapp.com/advisory/ntap-20190404-0001 https://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html • CWE-427: Uncontrolled Search Path Element •

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 •

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 •
