CVE-2019-0065 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. On MX Series, when the SIP ALG is enabled, receipt of a certain malformed SIP packet may crash the MS-PIC component on MS-MIC or MS-MPC. By continuously sending a crafted SIP packet, an attacker can repeatedly bring down MS-PIC on MS-MIC/MS-MPC causing a sustained Denial of Service. EPSS estimates a 1.27% chance of exploitation in the next 30 days.
