CVE-2025-58183 (GCVE-0-2025-58183)

Vulnerability from cvelistv5 – Published: 2025-10-29 22:10 – Updated: 2025-11-04 21:13

Title

Unbounded allocation when parsing GNU sparse map in archive/tar

Summary

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.

Severity ?

4.3 (Medium)
