CVE-2018-6345 (GCVE-0-2018-6345)

Vulnerability from cvelistv5 – Published: 2019-01-15 22:00 – Updated: 2024-08-05 06:01

Summary

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 ?

No CVSS data available.
