How to fix?

Upgrade Centos:8 file-libs to version 0:5.33-20.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream file-libs package and not the file-libs package as distributed by Centos:8. See How to fix? for Centos:8 relevant fixed versions and status.

cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).
