Descriptions

PuTTY before 0.73 might allow remote SSH-1 servers to cause a denial of service by accessing freed memory locations via an SSH1_MSG_DISCONNECT message.

PuTTY versiones anteriores a 0.73, podría permitir que los servidores remotos SSH-1 causen una denegación de servicio mediante el acceso a ubicaciones de memoria liberadas por medio de un mensaje SSH1_MSG_DISCONNECT.

An update that fixes two vulnerabilities is now available. This update for putty to version 0.73 fixes the following issues. Fixed the insufficient handling of terminal escape sequences, that should delimit the pasted data in bracketed paste mode. Fixed a possible information leak caused by SSH-1 disconnection messages.
