CVE-2018-5027
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 in Adobe Acrobat and Reader allows attackers to read memory contents beyond allocated buffers, potentially exposing sensitive information. The vulnerability affects multiple older versions across three major release branches (2015, 2017, and 2018).

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 Adobe Acrobat or Reader DC is installedOn Windows, open Control Panel > Programs and Features and look for 'Adobe Acrobat DC' or 'Adobe Acrobat Reader DC'. Alternatively, launch the application and go to Help > About Adobe Acrobat DC (or Reader).Affected if Neither Adobe Acrobat DC nor Adobe Acrobat Reader DC is installed (not affected).
-
Identify the exact installed versionIn the application, go to Help > About Adobe Acrobat DC (or Reader). The version number displays in the format XX.XXX.XXXXX.X (for example, 15.006.30060). Note the full version string exactly as shown.Affected if The installed version cannot be determined or the product is not Adobe Acrobat/Reader DC (detection inconclusive).
-
Compare version against affected range 1Check if your version falls between 15.006.30060 and 15.006.30418 (inclusive). Compare each numeric segment: 15.006.30060 <= your version <= 15.006.30418.Affected if Version is within this range (15.006.30060 to 15.006.30418) - likely affected.
-
Compare version against affected range 2Check if your version falls between 15.008.20082 and 18.011.20040 (inclusive). Compare each numeric segment: 15.008.20082 <= your version <= 18.011.20040.Affected if Version is within this range (15.008.20082 to 18.011.20040) - likely affected.
-
Compare version against affected range 3Check if your version falls between 17.011.30059 and 17.011.30080 (inclusive). Compare each numeric segment: 17.011.30059 <= your version <= 17.011.30080.Affected if Version is within this range (17.011.30059 to 17.011.30080) - likely affected.
If Adobe Acrobat DC or Reader DC is installed and the installed version matches any of the three affected ranges, the environment is vulnerable to CVE-2018-5027.
