CVE-2018-12757
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 · uneditedAdobe Acrobat and Reader 2018.011.20040 and earlier, 2017.011.30080 and earlier, and 2015.006.30418 and earlier versions have an Out-of-bounds read vulnerability. Successful exploitation could lead to information disclosure.
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 confidenceAn out-of-bounds read vulnerability exists in Adobe Acrobat and Reader across multiple version families (2018.x, 2017.x, and 2015.x). The vulnerability allows reading memory beyond allocated buffer boundaries, potentially exposing sensitive information from the application's memory space.

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.
-
Identify installed Adobe productOpen Windows Control Panel > Programs and Features, or check Start Menu for Adobe Acrobat or Adobe Acrobat Reader DC icons. Look for 'Acrobat DC' or 'Acrobat Reader DC' in the installed programs list.Affected if Either Adobe Acrobat DC or Adobe Acrobat Reader DC is installed (both are affected by this CVE)
-
Determine exact version numberIn the installed Adobe application, go to Help > About Adobe Acrobat DC (or Reader). The version number displays in the format like '15.006.30418' or '18.011.20040'. Record the full version string shown.Affected if The displayed version falls within any of the affected ranges (>= 15.006.30060 through <= 15.006.30418, OR >= 15.008.20082 through <= 18.011.20040, OR >= 17.011.30059 through <= 17.011.30080)
-
Verify product year familyThe first two digits of the version indicate the year family: 15.x = 2015 version, 17.x = 2017 version, 18.x = 2018 version. Cross-reference with the specific version range brackets above to confirm your exact version is listed as vulnerable.Affected if Your installed version matches any of the three specific vulnerable brackets listed in the affected versions
If Adobe Acrobat DC or Reader DC is installed AND its version number falls within any of the specified vulnerable ranges, the environment is affected by this out-of-bounds read vulnerability.

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 dataUpdate Adobe Acrobat and Reader to versions later than 2018.011.20040, 2017.011.30080, and 2015.006.30418 respectively, as patches were released to address this out-of-bounds read flaw.
