Descriptions
OCaml before 4.03.0 does not properly handle sign extensions, which allows remote attackers to conduct buffer overflow attacks or obtain sensitive information as demonstrated by a long string to the String.copy function.
OCaml en versiones anteriores a 4.03.0 no maneja correctamente extensiones de firma, lo que permite a atacantes remotos llevar a cabo ataques de desbordamiento de buffer u obtener información sensible según lo demostrado por una cadena larga para la función String.copy.
An integer conversion flaw was found in the way OCaml's String handled its length. Certain operations on an excessively long String could trigger a buffer overflow or result in an information leak.
