Junos OS: SRX Series and MX Series: Memory leak due to receipt of specially crafted SIP calls
An Improper Handling of Unexpected Data Type vulnerability in the handling of SIP calls in Juniper Networks Junos OS on SRX Series and MX Series platforms allows an attacker to cause a memory leak leading to Denial of Services (DoS).
