CVE-2017-15264
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 · uneditedIrfanView version 4.44 (32bit) allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .tif file, related to "Data from Faulting Address is used as one or more arguments in a subsequent Function Call starting at image00000000_00400000+0x00000000000236e4."
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 confidenceIrfanView 4.44 (32-bit) contains a memory corruption vulnerability when parsing crafted .tif files. The vulnerability occurs because data from a faulting address is used as arguments in a subsequent function call, indicating a write-what-where or similar memory corruption flaw that can cause denial of service or potentially allow 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 IrfanView installationCheck for IrfanView in program files or search for irfanview.exe on the systemAffected if IrfanView is installed on the system
-
Identify installed IrfanView versionRight-click irfanview.exe, select Properties, and check the Version tab, or run 'irfanview.exe /?' to display version infoAffected if The version shown is exactly 4.44 (32-bit build)
-
Verify application architectureCheck if the installed binary is 32-bit - look for 'Program Files (x86)' installation path or use a PE analysis tool to check the image typeAffected if The installed version is the 32-bit (x86) variant of IrfanView 4.44
-
Check TIFF file association statusLook for .tif file type associations in Windows default programs or check if IrfanView is set as the default handler for .tif filesAffected if IrfanView is associated as the handler for .tif files and the user opens a crafted malicious .tif file
You are affected if you have IrfanView version 4.44 (32-bit) installed and it is configured to open .tif files, as the vulnerability triggers when parsing a specially crafted .tif file.

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 unverified .tif files in IrfanView until a vendor patch is available. Consider using alternative image viewers or disabling TIFF file association for untrusted sources.
