CVE-2019-0169
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 · uneditedHeap overflow in subsystem in Intel(R) CSME before versions 11.8.70, 11.11.70, 11.22.70, 12.0.45; Intel(R) TXE before versions 3.1.70 and 4.0.20 may allow an unauthenticated user to potentially enable escalation of privileges, information disclosure or denial of service via adjacent access.
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 confidenceHeap overflow vulnerability in Intel CSME and TXE firmware allows an unauthenticated attacker with adjacent network access to potentially escalate privileges, disclose information, or cause denial of service. This is a firmware-level flaw in Intel's manageability engine subsystem.

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.
-
Check if Intel CSME firmware is presentIdentify the Intel Converged Security Management Engine firmware version on the system using Intel diagnostic tools or system information utilitiesAffected if The installed CSME version falls within: >= 11.0 and < 11.8.70, OR >= 11.10 and < 11.11.70, OR >= 11.20 and < 11.22.70, OR >= 12.0 and < 12.0.45
-
Check if Intel TXE firmware is presentIdentify the Intel Trusted Execution Engine firmware version on the system using Intel diagnostic tools or system information utilitiesAffected if The installed TXE version falls within: >= 3.0 and < 3.1.70, OR >= 4.0 and < 4.0.20
-
Determine network exposureVerify whether the system has adjacent network access to the CSME/TXE management interfaces (typically accessible via LAN or wireless interfaces)Affected if Adjacent network access to the Intel manageability engine subsystem is available and the firmware version is vulnerable
A system is affected if it contains Intel CSME or TXE firmware with a version matching any of the affected ranges listed and has adjacent network access to the manageability engine interface.

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 data3.1.704.0.2011.8.70
Apply Intel firmware updates: upgrade CSME to versions 11.8.70+, 11.11.70+, 11.22.70+, or 12.0.45+; upgrade TXE to versions 3.1.70+ or 4.0.20+ per Intel's firmware deployment guidelines.
