Description
The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked input for loop condition error in a NAT library. A local authenticated user can cause a Denial of Service (DoS).
When an inconsistent "deterministic NAT" configuration is present on an SRX, or MX with SPC3 and then a specific CLI command is issued the SPC will crash and restart.
Repeated execution of this command will lead to a sustained DoS.
