Descriptions
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.
