There is a workaround that addresses this vulnerability.
Examine the object groups that make up the ACL. If the same IPv4 source or destination or both appear more than 31 times in object groups that comprise the ACL, remove access control entries until there are 31 or fewer entries of the same IPv4 address in both the source and destination entries.
While this workaround has been deployed and was proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.
