CVE-2019-9135
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 versions have a Heap-based overflow vulnerability, triggered when the user opens a malformed DIB format 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 confidenceDaviewIndy 8.98.7 and earlier versions contain a heap-based buffer overflow when parsing malformed DIB (Device Independent Bitmap) format files. The vulnerability exists in Daview.exe due to improper bounds checking during DIB file handling, allowing attackers to achieve arbitrary code execution via specially crafted files.

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.
-
Confirm Daviewindy installationSearch for Daview.exe on the system using file search or check common program installation directories (e.g., C:\Program Files\DaviewIndy or C:\Program Files (x86)\DaviewIndy)Affected if Daview.exe is present on the system
-
Identify installed versionRight-click on Daview.exe, select Properties, then check the Details tab for the File Version. Alternatively, right-click the application shortcut and look for version information in the target path or file propertiesAffected if The reported version is 8.98.7 or earlier, or if no version information is displayed (which may indicate an unpatched older release)
-
Verify DIB file handling capabilityLaunch Daviewindy and attempt to open or import a DIB (Device Independent Bitmap) file. Check if the application includes DIB as a supported format in its file open dialog or documentationAffected if The application opens or processes DIB files and the version is 8.98.7 or earlier
-
Inspect application featuresReview the application's supported image formats list, typically found in Help > About or in the file open filter. Look for DIB, BMP, or device-independent bitmap format supportAffected if DIB format support is listed and the version is 8.98.7 or earlier
The environment is affected if Daviewindy version 8.98.7 or earlier is installed and the application is capable of opening or processing DIB files, as the heap overflow occurs during DIB file parsing in Daview.exe.

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 dataUsers should avoid opening DIB files from untrusted sources. If a patched version is unavailable, consider using application sandboxing, virtualization, or migrating to an alternative viewer. Contact the vendor for patch availability.
