CVE-2022-28257
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 · high confidenceThis is an out-of-bounds read vulnerability in Adobe Acrobat Reader DC's file parsing engine. When parsing a specially crafted PDF file, the application reads beyond the boundaries of allocated memory structures, leaking memory contents that can be used to defeat ASLR mitigations.

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 or Reader is installedCheck the Windows registry at HKLM\SOFTWARE\Adobe\Adobe Acrobat or HKLM\SOFTWARE\Adobe\Adobe Acrobat Reader DC, or look for AcroRd32.exe (Reader) or AcroBat.exe/Acrobat.exe (Acrobat) in Program FilesAffected if No Adobe Acrobat/Reader installation found means not affected by this CVE
-
Identify the exact installed version numberRight-click the executable (AcroRd32.exe or Acrobat.exe) in Program Files, select Properties, and read the File Version from the Details tab. Alternatively, run: wmic product where "name like 'Adobe Acrobat%'" get name,versionAffected if Unable to determine version means impact cannot be assessed
-
Compare Reader DC version against affected rangeIf using Adobe Acrobat Reader DC, compare the 4-digit version (such as 22.001.20085) against the range 15.008.20082 through 22.001.20085. Any version within or equal to these bounds is affected.Affected if Version falls within 15.008.20082 to 22.001.20085 inclusive indicates vulnerability
-
Compare Acrobat/Reader version 17 against affected rangeIf using version 17.x, compare against the range 17.011.30059 to 17.012.30205. Any version within or equal to these bounds is affected.Affected if Version falls within 17.011.30059 to 17.012.30205 inclusive indicates vulnerability
-
Compare Acrobat/Reader version 20 against affected rangeIf using version 20.x, compare against ranges 20.001.30005 to 20.005.30314 or 20.001.30005 to 20.005.30311. Any version within these bounds is affected.Affected if Version falls within 20.001.30005 to 20.005.30314 (or 20.005.30311) inclusive indicates vulnerability
The system is affected if Adobe Acrobat or Reader is installed and the detected version falls within any of the listed vulnerable ranges (15.008.20082-22.001.20085, 17.011.30059-17.012.30205, or 20.001.30005-20.005.30314/30311).
