How to fix?

Upgrade Centos:7 zlib to version 0:1.2.7-20.el7_9 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream zlib package and not the zlib package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
