NVD Description

Note: Versions mentioned in the description apply only to the upstream php:7.2/php-json package and not the php:7.2/php-json package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. A heap-based buffer over-read in PHAR reading functions in the PHAR extension may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse the file name, a different vulnerability than CVE-2018-20783. This is related to phar_detect_phar_fname_ext in ext/phar/phar.c.
