CVE-2020-7827
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 · uneditedDaviewIndy 8.98.7 and earlier version contain Use-After-Free vulnerability, triggered when the user opens a malformed specific file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.
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 confidenceDaviewIndy 8.98.7 and earlier versions contain a Use-After-Free vulnerability in Daview.exe where processing a malformed specific file causes improper memory handling, leading to freed memory being accessed. Attackers can exploit this for arbitrary code execution.

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 DaviewIndy is installedCheck for the presence of Daview.exe in the program files directory (typically C:\Program Files\DaviewIndy or C:\Program Files (x86)\DaviewIndy) or search for the file using: Get-ChildItem -Path "C:\Program Files","C:\Program Files (x86)" -Filter "Daview.exe" -Recurse -ErrorAction SilentlyContinueAffected if Daview.exe is found on the system
-
Determine installed versionRight-click on Daview.exe, select Properties, and check the File Version in the Details tab. Alternatively, run: (Get-Item "path\to\Daview.exe").VersionInfo.FileVersionAffected if The displayed version is 8.98.7 or earlier
-
Check file version via command lineUse WMIC or PowerShell to query the file version: wmic datafile where name='C:\Program Files\DaviewIndy\Daview.exe' get VersionAffected if Version returned is 8.98.7 or lower
-
Confirm vulnerable componentVerify the executable is the main Daview.exe application from Hmtalk Daviewindy by checking the product name in file properties under the Version tabAffected if Product is confirmed as DaviewIndy and version is <= 8.98.7
The system is affected if DaviewIndy (Daview.exe) version 8.98.7 or earlier is installed, as the use-after-free vulnerability exists in those versions when processing malformed files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAvoid opening untrusted or malformed files with DaviewIndy until the vendor releases a security patch addressing the memory management flaw in file parsing.
