CVE-2017-10779
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 xnview+0x0000000000013a20."
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 confidenceXnView Classic Version 2.40 contains a memory corruption vulnerability when parsing specially crafted .rle (Run-Length Encoded) image files. The vulnerability allows an attacker to control branch selection through faulting address data, potentially enabling denial of service or 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 is installedCheck for XnView installation directory (typically C:\Program Files\XnView or C:\Program Files (x86)\XnView) or search for xnview.exe on the systemAffected if XnView Classic executable is found on the system
-
Identify installed XnView versionRight-click xnview.exe, select Properties, then view the Details tab to see the File Version. Alternatively, launch XnView and go to Help > About to display the version numberAffected if The version displayed is exactly 2.40
-
Check .rle file associationSearch for .rle files on the system or check XnView's supported formats (Options > File Formats or File > Open dialog file type dropdown) to see if RLE is recognizedAffected if XnView is configured to open or recognize .rle files
-
Verify .rle parsing capabilityCheck if XnView's RLE format plugin (rle.* or similar format handler) exists in the XnView program folder or format configurationAffected if RLE format support is present and enabled in XnView
-
Assess exposure to untrusted RLE filesReview user behavior: determine if the system processes .rle files from untrusted sources (email attachments, downloads, network shares) through XnViewAffected if Users can open or preview .rle files from untrusted or external sources using XnView
A user is affected if XnView Classic version 2.40 is installed with .rle file handling enabled and users could open potentially malicious .rle files from untrusted sources.

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 .rle files in XnView Classic. Upgrade to a patched version if available, or implement file validation/endpoint protection to block malicious RLE files.
