How to fix?

Upgrade Oracle:8 libtar to version 0:1.2.20-17.el8 or higher.
This issue was patched in ELSA-2023-2898.

NVD Description

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

The th_read() function doesn’t free a variable t->th_buf.gnu_longlink after allocating memory, which may cause a memory leak.
