CVE-2019-1582
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 · uneditedMemory corruption in PAN-OS 8.1.9 and earlier, and PAN-OS 9.0.3 and earlier will allow an administrative user to cause arbitrary memory corruption by rekeying the current client interactive session.
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 · moderate confidenceA memory corruption vulnerability in Palo Alto Networks PAN-OS 8.1.9 and earlier, and PAN-OS 9.0.3 and earlier allows an authenticated administrative user to cause arbitrary memory corruption by rekeying the current client interactive session. This could lead to denial of service or potentially privilege escalation depending on the memory layout manipulation.

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.
-
Determine PAN-OS versionLog into the PAN-OS CLI and run 'show system info' or 'show version' to retrieve the installed PAN-OS version numberAffected if The version falls within 8.1.0 to 8.1.9 or 9.0.0 to 9.0.3 inclusive
-
Identify administrative accountsReview the list of administrative users configured on the device via the web interface under 'Device > Administrators' or via CLI command 'show admin user'Affected if Multiple administrative accounts exist, increasing the attack surface for an authenticated attacker
-
Check management interface exposureExamine the management profile and interface settings to determine if the PAN-OS management interface (port 443/80) is exposed to untrusted networks. Run 'show interface management' or review network zone configurationsAffected if The management interface is accessible from untrusted or external networks rather than only from trusted internal networks
-
Audit recent administrative session activityReview system logs and session logs for any session rekeying events. In the web interface, check 'Monitor > Logs > System' or use CLI 'show log system' looking for events around interactive session rekeyingAffected if Evidence of session rekeying activity by administrative users is found in the logs
A system is affected if it runs PAN-OS version 8.1.0 through 8.1.9 or 9.0.0 through 9.0.3 and has an authenticated administrative user who could trigger the session rekeying action.

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 dataUpgrade PAN-OS to a version beyond 8.1.9 and 9.0.3 (refer to Palo Alto Networks security advisory for fixed versions). Restrict administrative access to trusted personnel and monitor for suspicious session rekeying activity.
