CVE-2022-28261
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 22.001.2011x (and earlier), 20.005.3033x (and earlier) and 17.012.3022x (and earlier) are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. 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 · moderate confidenceAdobe Acrobat Reader DC contains an out-of-bounds read vulnerability when parsing specially crafted PDF files. The vulnerability allows reading past the end of an allocated memory structure, potentially exposing memory addresses that could be used to bypass ASLR. Exploitation requires a victim to open a malicious PDF file.

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.
-
Locate installed Adobe Acrobat or Reader versionOpen Adobe Acrobat/Reader, then go to Help > About Adobe Acrobat Reader (or About Adobe Acrobat). The version number is displayed in the dialog box. Alternatively, on Windows check the program properties in Control Panel > Programs and Features, or on macOS check the application in Applications folder using Get Info.Affected if Version falls within any of the affected ranges: 15.008.20082 through 22.001.20085 for DC variants; 17.011.30059 through 17.012.30205, 20.001.30005 through 20.005.30314, or 20.001.30005 through 20.005.30311 for classic versions.
-
Confirm product variant and buildIdentify whether the installation is Acrobat DC, Acrobat Reader DC, classic Acrobat, or classic Acrobat Reader. The version number format differs by product line. DC versions typically show a year-month format (e.g., 22.001.20085), while classic versions show a year format (e.g., 20.005.30314).Affected if The version matches the affected range for that specific product variant.
-
Verify PDF handling capability is activeConfirm the software has not been configured to disable PDF opening or to use a different PDF handler. Check if the software can open and render PDF documents normally.Affected if PDF files can be opened by the installed Adobe software, meaning the parsing component that contains the vulnerability is functional.
A user is affected if Adobe Acrobat or Acrobat Reader is installed with a version number matching any of the specified vulnerable ranges and the application can open PDF files.
