Doc Text:
A vulnerability in Rubyzip, versions prior to 1.3.0, allows a crafted ZIP file to bypass application checks on ZIP entry sizes. This allows an attacker to spoof data regarding the uncompressed size of the ZIP file, causing a denial of service due to disk consumption. Availability of the system is the highest threat.
