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 that allows reading memory outside the intended buffer boundaries. Successful exploitation could allow an attacker to leak sensitive information from the application's memory space, potentially exposing credentials, session tokens, or other confidential data.
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.
-
Check if Adobe Acrobat or Reader is installedOn Windows, open Programs and Features or look in C:\Program Files\Adobe\ for Acrobat or Reader folders. On macOS, check /Applications for Adobe Acrobat or Adobe Acrobat Reader.Affected if Adobe Acrobat DC or Adobe Acrobat Reader DC is present on the system
-
Locate the installed version numberRight-click the Adobe Acrobat or Reader executable (e.g., AcroRd32.exe or AcroTray.exe) in Program Files, select Properties, and view the Details tab for the Product Version. Alternatively, open the application and go to Help > About Adobe Acrobat Reader.Affected if A version number is found that falls within the affected ranges
-
Compare installed version against vulnerable rangesCompare your exact version number (e.g., 19.021.20055) against these affected ranges: 15.006.30060 through 15.006.30507, 15.008.20082 through 19.021.20057, and 17.011.30059 through 17.011.30155.Affected if The installed version is greater than or equal to 15.006.30060 AND less than 15.006.30508, OR greater than or equal to 15.008.20082 AND less than 19.021.20058, OR greater than or equal to 17.011.30059 AND less than 17.011.30156
If Adobe Acrobat DC or Reader DC is installed with a version matching any of the affected ranges listed, the system is vulnerable to out-of-bounds memory read and may leak sensitive application memory contents.
