Description

The affected asset is vulnerable to this vulnerability ONLY if it is running one of the following modules: mod_deflate. Review your web server configuration for validation. A denial of service flaw was found in the mod_deflate module. This module continued to compress large files until compression was complete, even if the network connection that requested the content was closed before compression completed. This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file.
