A vulnerability in Rubyzip, versions prior to 1.3.0, allows a crafted ZIP file to bypass application checks on ZIP entry sizes.

Description Dhananjay Arunesh 2019-11-12 06:52:23 UTC
A vulnerability was found 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).
