How to fix?

Upgrade Centos:8 glibc-utils to version 0:2.28-151.el8 or higher.

NVD Description

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

The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.
