CVE-2018-5022
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 confidenceThis is an out-of-bounds read vulnerability in Adobe Acrobat and Reader. The vulnerability exists in the listed versions where the software reads memory beyond allocated buffer boundaries, potentially allowing an attacker to access sensitive information stored in process memory.

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 Adobe Acrobat DC or Reader DC is installedOpen Windows Control Panel > Programs and Features, or on macOS open Applications folder, and look for Adobe Acrobat DC or Adobe Acrobat Reader DC in the installed software listAffected if Either Adobe Acrobat DC or Adobe Acrobat Reader DC is present on the system
-
Find the installed version numberRight-click on the Adobe application in Programs and Features and select Properties, or open the application and go to Help > About Adobe Acrobat/Reader DC to display the exact version number (for example: 15.006.30418 or 18.011.20040)Affected if The exact version displayed matches one of the affected version ranges
-
Compare version against the first affected rangeCheck if the installed version falls between 15.006.30060 and 15.006.30418 (inclusive), or between 15.008.20082 and 15.008.30418 (if present in your version display)Affected if The version is within this range (15.006.30060 to 15.006.30418 or 15.008.20082 to 15.008.30418)
-
Compare version against the second affected rangeCheck if the installed version falls between 17.011.30059 and 17.011.30080 (inclusive)Affected if The version is within 17.011.30059 to 17.011.30080
-
Compare version against the third affected rangeCheck if the installed version falls between 18.011.20082 and 18.011.20040 (inclusive) - note that the lower bound appears to be 15.008.20082 based on the patternAffected if The version is within 15.008.20082 to 18.011.20040 range
The system is affected if Adobe Acrobat DC or Reader DC is installed and the version number falls within any of the listed vulnerable ranges (15.006.30060-15.006.30418, 15.008.20082-18.011.20040, or 17.011.30059-17.011.30080).

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 a version newer than 2018.011.20040, 2017.011.30080, or 2015.006.30418 respectively, or apply the vendor-supplied security patches.
