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 · unedited
Juniper Junos 10.4S before 10.4S15, 10.4R before 10.4R16, 11.4 before 11.4R9, and 12.1R before 12.1R7 on SRX Series service gateways allows remote attackers to cause a denial of service (flowd crash) via a crafted IP packet.

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 confidence

Denial of service vulnerability in Juniper SRX Series service gateways running Junos 10.4S before 10.4S15, 10.4R before 10.4R16, 11.4 before 11.4R9, and 12.1R before 12.1R7. Remote attackers can send a crafted IP packet to crash the flowd process, causing service disruption.

MitigationUpgrade Junos to version 10.4S15, 10.4R16, 11.4R9, 12.1R7 or later. If immediate upgrade is not possible, consider network segmentation or IDS/IPS filtering to block malformed packets.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model and confirm it is an SRX Series gateway
    Run 'show chassis hardware' or 'show system information' to confirm the device is one of: Srx100, Srx110, Srx1400, Srx210, Srx220, Srx240, or Srx3400
    Affected if Device is any of these SRX models running any version
  2. Determine the exact Junos version installed
    Run 'show version' or 'show system version' to retrieve the installed Junos software version
    Affected if Version is 10.4S before S15, 10.4R before R16, 11.4 before R9, or 12.1R before R7
  3. Verify the flowd process is running
    Run 'show system processes' or 'ps aux | grep flowd' to confirm the flow daemon (flowd) is active
    Affected if Flowd process is running and handling traffic
  4. Check if the device is network-accessible to untrusted inputs
    Review interface configurations with 'show interfaces' and verify security zone policies to determine if the device accepts IP traffic from untrusted networks
    Affected if Device accepts IP packets from remote/untrusted sources on any interface

The environment is affected if the device is an SRX model running a vulnerable Junos version (10.4S<S15, 10.4R<R16, 11.4<R9, 12.1R<R7) and has flowd active with exposure to untrusted network traffic.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Junos to version 10.4S15, 10.4R16, 11.4R9, 12.1R7 or later. If immediate upgrade is not possible, consider network segmentation or IDS/IPS filtering to block malformed packets.
