Описание
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).
Отчет
Red Hat Enterprise Linux 8 is not affected by this vulnerability because ships already patched version of tar.
