CVE-2018-5058
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 a Heap Overflow vulnerability. Successful exploitation could lead to arbitrary code execution in the context of the current user.
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 confidenceHeap overflow vulnerability in Adobe Acrobat and Reader allows writing beyond allocated heap memory boundaries, potentially corrupting adjacent data structures and enabling arbitrary code execution with the current user's privileges. The vulnerability exists in PDF processing functionality and is triggered when parsing specially crafted PDF files.

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 if Adobe Acrobat or Reader is installedOn Windows, check for installation in C:\Program Files\Adobe\Acrobat DC\ or C:\Program Files (x86)\Adobe\Acrobat Reader DC\. On macOS, check /Applications for Adobe Acrobat or Adobe Reader.Affected if The product is present on the system
-
Determine the installed versionOpen the application, go to Help > About Adobe Acrobat or About Adobe Reader. Alternatively, on Windows right-click the executable (Acrobat.exe or AcroRd32.exe) in the installation folder and select Properties > Details to view the File Version.Affected if A version number is displayed or found in file properties
-
Compare your version against affected rangesMatch your installed version (fourth numeric segment, e.g., 18.011.20040) against these vulnerable ranges: 15.006.30060-15.006.30418, 15.008.20082-18.011.20040, 17.011.30059-17.011.30080.Affected if The installed version falls within any of these ranges
-
Verify PDF processing is in useThe vulnerability triggers when parsing PDF files. This is core functionality enabled by default. No additional configuration check needed if the product is installed.Affected if Adobe Acrobat or Reader is installed and able to open PDF files
If Adobe Acrobat DC or Acrobat Reader DC is installed and the version falls within 15.006.30060-15.006.30418, 15.008.20082-18.011.20040, or 17.011.30059-17.011.30040, the environment is affected by this vulnerability.
