The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the pdfseparate utility when handling PDF files. A remote attacker can pass a specially crafted PDF file to the application, consume all available system resources and cause denial of service conditions.
