Name of the Vulnerable Software and Affected Versions Rubyzip versions prior to 1.3.0

Description A crafted ZIP file can bypass application checks on ZIP entry sizes because data about the uncompressed size can be spoofed, allowing attackers to cause a denial of service (disk consumption).

Recommendations For versions prior to 1.3.0, update to version 1.3.0 or later to resolve the issue. As a temporary workaround, consider restricting the handling of ZIP files from untrusted sources to minimize the risk of exploitation.
