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 · unedited
Adobe Acrobat Reader versions 2019.010.20098 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

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 confidence

Out-of-bounds read vulnerability in Adobe Acrobat Reader versions 2019.010.20098 and earlier allows disclosure of sensitive memory beyond allocated buffers. This information leak can enable attackers to bypass ASLR mitigation by revealing memory addresses. Exploitation requires user interaction via opening a malicious file.

MitigationUpdate Adobe Acrobat Reader to a version later than 2019.010.20098. Additionally, educate users to avoid opening untrusted PDF files and consider email gateway scanning to block malicious attachments.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Adobe Acrobat Reader DC or Adobe Acrobat DC is installed
    On Windows, check for the presence of Adobe Acrobat Reader DC or Adobe Acrobat DC in the installed programs list (Control Panel > Programs and Features) or use command: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Adobe*Acrobat*'}
    Affected if Either Adobe Acrobat Reader DC or Adobe Acrobat DC is present on the system
  2. Determine the installed version number
    In Windows Programs and Features, locate the Version column for the Adobe product. Alternatively, right-click the Adobe Acrobat or Reader executable in Program Files and view Properties > Details to find the Product Version
    Affected if The version cannot be determined or is not visible in the properties
  3. Compare installed version against affected ranges
    Check if the installed version falls within any of these ranges: 15.000.00000 to 15.006.30482, 17.000.00000 to 17.011.30127, or 19.000.00000 to 19.010.20098. Version 19.010.20098 and earlier in the 19.x line is affected
    Affected if The installed version number is greater than 15.006.30482 but less than 17.000.00000, OR greater than 17.011.30127 but less than 19.000.00000, OR falls within 19.000.00000 to 19.010.20098

The environment is affected if Adobe Acrobat Reader DC or Adobe Acrobat DC is installed with a version matching any of the three vulnerable ranges (15.x up to 15.006.30482, 17.x up to 17.011.30127, or 19.x up to 19.010.20098).
