**Name of the Vulnerable Software and Affected Versions** zebedee versions prior to 2.5.3 **Description** The issue allows remote attackers to cause a denial of service, potentially leading to disruption of protected information availability. This can be triggered by a zero in the port number of the protocol option header, which causes an assert error in the `makeConnection` function in `zebedee.c`. **Recommendations** For versions prior to 2.5.3, update to version 2.5.3 or later to resolve the issue. As a temporary workaround, consider setting the "allowed redirection port" to prevent remote attackers from causing a denial of service.
