What is CVE-2019-18817?

In Istio versions 1.3.x prior to 1.3.5, a configuration flaw allows an attacker to trigger a Denial of Service. The issue arises due to the 'continue_on_listener_filters_timeout' setting being enabled, which does not handle timeouts appropriately. This vulnerability may lead to service disruptions, making it essential for users to upgrade to the latest version to mitigate potential risks. Additional details can be found in the Istio release notes and GitHub issue discussions.
