CVE-2018-15940
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 versions 2018.011.20063 and earlier, 2017.011.30102 and earlier, and 2015.006.30452 and earlier have an out-of-bounds write vulnerability. Successful exploitation could lead to arbitrary code execution.
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 confidenceAdobe Acrobat and Reader contain an out-of-bounds write vulnerability where the software writes data beyond the allocated memory buffer boundaries. This memory corruption can be exploited to execute arbitrary code with the privileges of the targeted user.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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.
-
Verify Adobe Acrobat or Reader is installedCheck for Adobe Acrobat DC or Adobe Acrobat Reader DC in the list of installed programs (Windows: Control Panel > Programs and Features, macOS: Applications folder)Affected if Either Adobe Acrobat DC or Adobe Acrobat Reader DC is present on the system
-
Identify the installed version numberOpen Adobe Acrobat/Reader, go to Help > About Adobe Acrobat DC (or About Adobe Reader DC) to display the version number, or check the Windows Registry at HKLM\SOFTWARE\Adobe\Adobe Acrobat\DC\Version or HKLM\SOFTWARE\Adobe\Adobe Reader\DC\VersionAffected if A version number is displayed or found in the registry
-
Compare against affected version rangesMatch the installed version (for example, 15.008.20082) against the three affected ranges: 15.006.30060 through 15.006.30452, 15.008.20082 through 18.011.20063, or 17.011.30059 through 17.011.30102Affected if The installed version falls within any of these ranges, meaning the out-of-bounds write vulnerability is present
If Adobe Acrobat DC or Reader DC is installed and the version number falls within any of the three affected ranges (15.006.30060-15.006.30452, 15.008.20082-18.011.20063, or 17.011.30059-17.011.30102), the system is vulnerable to CVE-2018-15940.
