Vulnerability from github – Published: 2022-05-13 01:16 – Updated: 2022-05-13 01:16

Details

The function number_format is vulnerable to a heap overflow issue when its second argument ($dec_points) 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).

Severity

9.8 (Critical)
