Descriptions

The mcrypt_create_iv function in hphp/runtime/ext/mcrypt/ext_mcrypt.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 does not seed the random number generator, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging the use of a single initialization vector.

La función mcrypt_create_iv en hphp/runtime/ext/mcrypt/ext_mcrypt.cpp en Facebook HipHop Virtual Machine (HHVM) anterior a 3.3.0 no inicializa el generador de números aleatorios, lo que hace que sea más fácil para los atacantes derrotar los mecanismos de protección criptográficos mediante el aprovechamiento del uso de único vector de inicialización
