CVE-2017-10751
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 · uneditedXnView Classic for Windows Version 2.40 might allow attackers to cause a denial of service or possibly have unspecified other impact via a crafted .rle file, related to "Data from Faulting Address controls Branch Selection starting at GDI32!GenericEngineGetGlyphs+0x0000000000000133."
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 confidenceXnView Classic v2.40 fails to properly handle specially crafted .rle (Run-Length Encoded) image files, leading to memory corruption in GDI32.dll's GenericEngineGetGlyphs function where data from a faulting address controls branch selection. This indicates a type confusion or arbitrary memory read vulnerability that can be triggered by opening a malicious .rle file, resulting in denial of service (application crash) or potentially 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.
-
Confirm XnView Classic installationCheck for XnView Classic in installed programs (Windows: Programs and Features, Linux: package manager, or locate xnview executable)Affected if XnView Classic version 2.40 is installed
-
Verify XnView version numberLaunch XnView and check Help > About, or right-click xnview.exe and view Properties > Details for File VersionAffected if Version is exactly 2.40
-
Check ability to open .rle filesAttempt to open a .rle file with XnView, or check if .rle file association exists in XnView's Tools > Options > File AssociationsAffected if XnView can process or is associated with .rle files
-
Inspect GDI32.dll presenceVerify Windows\System32\gdi32.dll exists on the system (the vulnerable function GenericEngineGetGlyphs is in this DLL)Affected if gdi32.dll is present and XnView uses GDI for image rendering
A user is affected if XnView Classic version 2.40 is installed and can open or process .rle image files, as this triggers the memory corruption in GDI32.dll.

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 dataApply vendor-supplied patch/update to XnView Classic if available; otherwise, restrict access to untrusted .rle files and consider using alternative image viewing software until a patch is released.
