NVD Description

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

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