Descriptions

content_encoding.c in libcurl 7.10.5 through 7.19.7, when zlib is enabled, does not properly restrict the amount of callback data sent to an application that requests automatic decompression, which might allow remote attackers to cause a denial of service (application crash) or have unspecified other impact by sending crafted compressed data to an application that relies on the intended data-length limit.

content_encoding.c en libcurl v7.10.5 hasta v7.19.7, cuando zlib está habilitado, no restringe adecuadamente la cantidad de datos de llamadas devueltas, enviadas a una aplicación que descomprime automaticamente las peticiones, lo que podría permitir a un atacante remoto provocar una denegación de servicio (caída de aplicación) o tener o tro impacto sin especificar mediante el envío de datos comprimidos manipulados a una aplicación que se basa en el límite destinado data-length.
