0 tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations. Join the discussion | CVE Database V5 | 10/29/2025, 22:10:14 UTC Added: 10/29/2025, 22:24:04 UTC |
