Descriptions

The HashContext class in hphp/runtime/ext/ext_hash.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 incorrectly expects that a certain key string uses '\0' for termination, which allows remote attackers to obtain sensitive information by leveraging read access beyond the end of the string, and makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging truncation of a string containing an internal '\0' character.

La clase HashContext en hphp/runtime/ext/ext_hash.cpp en Facebook HipHop Virtual Machine (HHVM) anterior a 3.3.0 espera incorrectamente que una clave use '\0' para finalizar, lo que permite a atacantes remotos obtener información sensible aprovechando el acceso de lectura más allá del final de la cadena, y esto hace más fácil para los atacantes remotos derrotar los mecanismos de protección criptográficos aprovechando el truncamiento de una cadena que contiene internamente el carácter '\0'.
