Summary
[none]
Details

The function numberformat is vulnerable to a heap overflow issue when its second argument ($decpoints) is excessively large. The internal implementation of the function will cause a string to be created with an invalid length, which can then interact poorly with other functions. This affects all supported versions of HHVM (3.30.1 and 3.27.5 and below).
