CVE-2020-7822
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 has a Heap-based overflow vulnerability, triggered when the user opens a malformed image 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 · moderate confidenceHeap-based buffer overflow in DaviewIndy (Daview.exe) when processing malformed image files. The application fails to properly validate or bound-check image data during parsing, allowing an attacker to overflow the heap and achieve 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.
-
Locate DaviewIndy installationSearch for Daview.exe on the system using file search or check common installation directories (typically C:\Program Files\DaviewIndy or C:\Program Files (x86)\DaviewIndy)Affected if Daview.exe exists on the system
-
Determine installed versionRight-click Daview.exe, select Properties, then look at the Version tab to find the product version. Alternatively, right-click the file in Windows Explorer, select Properties > Details to view File Version and Product VersionAffected if Version is 8.98.7 or lower (any version <= 8.98.7)
-
Verify image parsing is possibleCheck if the application has the capability to open or preview image files (JPG, PNG, BMP, GIF, or other image formats). This is typically visible in the file open dialog filter or in the application's supported formats documentationAffected if Image file format support is present in the installed version
-
Review recent file access activityCheck Windows Event Logs (Security and Application logs) for recent Daview.exe activity, or review the application's recent files list if available, to see if it has been used to open image filesAffected if DaviewIndy has been used to open image files from untrusted sources
The system is affected if DaviewIndy version 8.98.7 or lower is installed and the application is used to process image files, as the heap overflow occurs during malformed image parsing.

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 image files with DaviewIndy. Implement proper input validation and bounds checking in the image parsing routines. Consider deploying endpoint detection and monitoring until a vendor patch is available.
