Does this matter?
Lower severity and a low EPSS score (1.58%). Track it; it rarely justifies an emergency change on its own.
Description
In Rubyzip before 1.3.0, a crafted ZIP file can bypass application checks on ZIP entry sizes because data about the uncompressed size can be spoofed. This allows attackers to cause a denial of service (disk consumption).
