CVE-2022-44520
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 · uneditedAcrobat Reader DC version 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) are affected by a use-after-free vulnerability that could result in arbitrary code execution in the context of the current user. 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.

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 installationOpen Windows Control Panel > Programs and Features, or check the installation directory (typically C:\Program Files\Adobe\Acrobat DC\ or C:\Program Files (x86)\Adobe\Acrobat Reader DC\)Affected if Adobe Acrobat or Acrobat Reader DC is installed
-
Determine installed versionIn Adobe Acrobat/Reader, go to Help > About Adobe Acrobat (or About Adobe Reader). Alternatively, right-click the executable in the installation folder and select Properties > Details to view the File VersionAffected if Version falls within any of these ranges: 15.008.20082 through 22.001.20085, 17.011.30059 through 17.012.30205, or 20.001.30005 through 20.005.30314 (or 20.005.30311 depending on build)

Confirm vulnerability trigger conditionThe vulnerability requires a user to open a maliciously crafted PDF file. No special feature or service need be enabled for the flaw to apply.Affected if The affected version is installed AND a user opens a specially crafted PDF file
You are affected if Adobe Acrobat or Acrobat Reader DC is installed with a version number within the affected ranges (15.008.20082 to 22.001.20085, 17.011.30059 to 17.012.30205, or 20.001.30005 to 20.005.30314) and a malicious PDF is opened.
