Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of syntactic correctness of input error in Packet Forwarding Engine (PFE). A remote non-authenticated attacker can cause Denial of Service (DoS).
On all Junos OS MX Series and SRX Series platforms, when SIP ALG is enabled, and a specific SIP packet is received and processed, NAT IP allocation fails for genuine traffic, which causes Denial of Service (DoS).
Continuous receipt of this specific SIP ALG packet will cause a sustained DoS condition.
