Denial of service vulnerability in Ubuntu via a sparse.c fileID: oval:org.secpod.oval:def:50591 | Date: (C)2019-02-01 (M)2023-12-20 |
Class: VULNERABILITY | Family: unix |
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).
