CVE-2019-0075
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the srxpfe process on Protocol Independent Multicast (PIM) enabled SRX series devices may lead to crash of the srxpfe process and an FPC reboot while processing (PIM) messages. Sustained receipt of these packets may lead to an extended denial of service condition. Affected releases are Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D80; 15.1X49 versions prior to 15.1X49-D160; 17.3 versions prior to 17.3R3-S7 17.4 versions prior to 17.4R2-S8, 17.4R3; 18.1 versions prior to 18.1R3-S8; 18.2 versions prior to 18.2R2; 18.3 versions prior to 18.3R2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA memory handling flaw exists in the srxpfe process on SRX series firewalls with Protocol Independent Multicast (PIM) enabled. When malformed PIM packets are received, the srxpfe process crashes, causing an FPC reboot. Repeated packet receipt can sustain this denial of service condition.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm SRX series modelRun 'show chassis hardware' or check the device model via 'show system information' to verify the device is an SRX series firewallAffected if Device is not an SRX model - the vulnerability only affects SRX series
-
Check Junos versionRun 'show version' to obtain the installed Junos OS versionAffected if Version matches or falls within 12.3x48, 15.1x49, 17.3, 17.4, 18.1, 18.2, or 18.3 branches (prior to fixed releases)
-
Verify PIM is enabledRun 'show configuration protocols pim' or check the configuration under 'set protocols pim' to determine if Protocol Independent Multicast is configuredAffected if PIM is enabled - the flaw only triggers when malformed PIM packets are received on a PIM-enabled interface
A user is affected if they have an SRX series firewall running a vulnerable Junos version listed above with PIM protocol enabled, as the crash only occurs when malformed PIM packets are received on PIM-enabled interfaces.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the appropriate Junos OS patch for your version branch (12.3X48-D80+, 15.1X49-D160+, 17.3R3-S7+, 17.4R2-S8+, 17.4R3+, 18.1R3-S8+, 18.2R2+, 18.3R2+) after scheduling a maintenance window to minimize service disruption.
