Unbounded allocation when parsing GNU sparse map in archive/tar_CVE-2025-58183

{
    "lastseen": "",
    "description": "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.",
