Descriptions

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).

En Rubyzip versiones anteriores a 1.3.0, un archivo ZIP diseñado puede omitir las comprobaciones de la aplicación en los tamaños de entrada ZIP porque los datos sobre el tamaño sin comprimir pueden ser falsificados. Esto permite a atacantes causar una denegación de servicio (consumo de disco).

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.
