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 · moderate confidenceThis is an out-of-bounds read vulnerability in Adobe Acrobat and Reader. The vulnerability occurs when the software reads memory outside the intended buffer boundaries, potentially allowing an attacker to read sensitive information from the application's memory space. Successful exploitation leads to information disclosure but does not directly allow code execution.

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.
-
Locate the Adobe Acrobat or Reader installationOpen Windows Explorer and navigate to the installation directory, typically C:\Program Files\Adobe\Acrobat DC or C:\Program Files (x86)\Adobe\Acrobat DC. Locate theAcrobat.exe or AcroRd32.exe file.Affected if The executable exists on the system and the version falls within the affected ranges listed below.
-
Determine the installed version from file propertiesRight-click on Acrobat.exe (for Acrobat) or AcroRd32.exe (for Reader), select Properties, then go to the Details tab. Note the Product Version and File Version fields.Affected if The version number matches one of these vulnerable ranges: 15.006.30060 through 15.006.30418, 15.008.20082 through 18.011.20040, or 17.011.30059 through 17.011.30080.
-
Check version via the application Help menuOpen Adobe Acrobat or Reader, click Help, then select About Adobe Acrobat (or About Adobe Reader). The version number displays in the dialog that appears.Affected if The displayed version falls within any of the vulnerable ranges specified in step 2.
-
Query version via Windows Registry (optional alternative)Open Registry Editor and navigate to HKLM\SOFTWARE\Adobe\Adobe Acrobat\DC\Version (or the corresponding key for Reader). Read the (Default) or Version value.Affected if The registry version value matches any of the affected ranges listed in step 2.
A user is affected if Adobe Acrobat DC or Adobe Acrobat Reader DC is installed with a version number matching any of the three vulnerable ranges: 15.006.30060-15.006.30418, 15.008.20082-18.011.20040, or 17.011.30059-17.011.30080.
