Faktory is a language-agnostic persistent background job server. Prior to version 1.8.0, the Faktory web dashboard can suffer from denial of service by a crafted malicious url query param days. The vulnerability is related to how the backend reads the days URL query parameter in the Faktory web dashboard. The value is used directly without any checks to create a string slice. If a very large value is provided, the backend server ends up using a significant amount of memory and causing it to crash. Version 1.8.0 fixes this issue.
