Descriptions

Multiple buffer overflows in libtidy, as used in the Tidy extension for PHP 5.2.3 and possibly other products, allow context-dependent attackers to execute arbitrary code via (1) a long second argument to the tidy_parse_string function or (2) an unspecified vector to the tidy_repair_string function. NOTE: this might only be an issue in environments where vsnprintf is implemented as a wrapper for vsprintf.

Múltiples desbordamientos de búfer en libtidy, como es usado en la extensión Tidy para PHP versión 5.2.3 y posiblemente otros productos, permiten a atacantes dependiendo del contexto ejecutar código arbitrario por medio de (1) un segundo argumento largo en la función tidy_parse_string o (2) un vector no especificado en la función tidy_repair_string. NOTA: esto solo puede ser un problema en entornos donde vsnprintf se implementa como un contenedor para vsprintf.
