NVD Description

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

GNU Tar through 1.30, when --sparse is used, mishandles file shrinkage during read access, which allows local users to cause a denial of service (infinite read loop in sparse_dump_region in sparse.c) by modifying a file that is supposed to be archived by a different user's process (e.g., a system backup running as root).
