NVD Description
Note: Versions mentioned in the description apply only to the upstream php7-wddx package and not the php7-wddx package as distributed by SLES.
See How to fix? for SLES:15.0 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.
