| Doc Text: |
A flaw was found in Go's `archive/tar` package. A remote attacker could exploit this vulnerability by providing a maliciously-crafted archive file. When the `tar.Reader` processes an archive containing a large number of sparse regions in the "old GNU sparse map" format, it can lead to unbounded memory allocation. This can result in a Denial of Service (DoS) condition, making the affected application unresponsive.
