Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to double free error when handling a user-supplied input. A remote attacker can send specially crafted fragmented data, trigger a double-free memory error in the Traffic Management Microkernel (TMM) and cause the TMM to crash, interrupting traffic processing while the TMM restarts.
Successful exploitation of the vulnerability results in denial of service.
