NVD Description

Note: Versions mentioned in the description apply only to the upstream php7 package and not the php7 package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

In PHP before 5.6.39, 7.x before 7.0.33, 7.1.x before 7.1.25, and 7.2.x before 7.2.13, a buffer over-read in PHAR reading functions may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse a .phar file. This is related to phar_parse_pharfile in ext/phar/phar.c.
