CVE-2018-1000024
First published: Mon Jan 22 2018(Updated: )
Due to incorrect pointer handling, Squid versions 3.x (prior to 3.5.27) and 4.x (prior to 4.0.23) are vulnerable to a denial of service attack when processing ESI responses. This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service.
