Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when processing IP packets. A remote attacker can send specially crafted IP packets with "ip proto" set to "0" and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that flow rules contain 'set' actions on other fields in the IP protocol header.

Mitigation

Install updates from vendor's website.
