Descriptions

Multipart-file uploads call variables to be improperly registered in the global scope. In cases where variables are not declared explicitly before being used this can lead to unexpected behavior. This affects all supported versions of HHVM prior to the patch (3.25.1, 3.24.5, and 3.21.9 and below).

Subidas del tipo "Multipart-file" llaman a variables para que se registren indebidamente en el ámbito global. En los casos en los que las variables no se declaran explícitamente antes de usarse, esto puede provocar un comportamiento no esperado. Esto afecta a todas las versiones soportadas de HVVM antes del parche (en versiones anteriores a las 3.25.1, 3.24.5 y 3.21.9).
