Descriptions

The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted tags in a YAML document, which triggers a heap-based buffer overflow.

La función yaml_parser_scan_tag_uri en scanner.c en LibYAML anterior a 0.1.5 lleva a cabo un "cast" incorrecto, lo que permite a atacantes remotos causar una denegación de servicio (caída de la aplicación) y probablemente ejecutar código arbitrario a través de etiquetas manipuladas en YAML.
