CVE-2022-28233
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 versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) are affected by a use-after-free vulnerability in the processing of annotations 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.
dbcve analysis · high confidenceThis is a use-after-free vulnerability in Adobe Acrobat Reader DC's annotation processing. When annotations in a PDF are processed, memory is freed but then accessed again, leading to arbitrary code execution in the context of the current 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.
-
Identify installed Adobe productCheck for installed Adobe Acrobat or Reader DC by looking in Add/Remove Programs (appwiz.cpl), or check the installation directory typically at C:\Program Files\Adobe\Acrobat DC\ or C:\Program Files (x86)\Adobe\Acrobat DC\Affected if Neither Adobe Acrobat DC nor Adobe Acrobat Reader DC is installed, then not affected
-
Determine exact version numberRight-click the Acrobat or Reader executable (Acrobat.exe or AcroRd32.exe) in the installation folder, select Properties, and view the File Version on the Details tabAffected if The installed version falls within any of these ranges: 15.008.20082 through 22.001.20085, 17.011.30059 through 17.012.30205, 20.001.30005 through 20.005.30314, or 20.001.30005 through 20.005.30311
-
Confirm product type and channelVerify whether the installation is Adobe Acrobat DC, Adobe Acrobat Reader DC, Adobe Acrobat (Classic), or Adobe Acrobat Reader (Classic) by checking the product name in Add/Remove Programs or the folder structure under C:\Program Files\Adobe\Affected if Product is Adobe Acrobat or Reader (either DC or Classic) and version is within the affected ranges listed above
User is affected if Adobe Acrobat or Reader (DC or Classic) is installed with a version matching any of the affected version ranges, since the use-after-free flaw exists in the annotation processing component for all these installations within those versions.
