CVE-2017-10733
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) 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 ntdll_77df0000!RtlpEnterCriticalSectionContended+0x0000000000000031."
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 in its RLE image file parser. When processing a specially crafted .rle file, the parser causes a heap buffer overflow or underflow that corrupts memory, leading to controlled branch selection at ntdll!RtlpEnterCriticalSectionContended. This can cause denial of service (crash) and 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.
-
Identify installed IrfanView versionLocate the IrfanView executable (typically in Program Files or Program Files (x86)) and check its file properties for version information, or use: right-click irfanview.exe > Properties > Details tabAffected if Version is exactly 4.44
-
Confirm 32-bit architectureCheck if the installed IrfanView is the 32-bit version. In the file properties under the Details tab, verify the product is not the 64-bit variant, or check if the installation path contains 'Program Files (x86)'Affected if The installed version is the 32-bit (x86) build of IrfanView 4.44
-
Verify RLE plugin availabilityCheck for the presence of RLE-related plugins in the IrfanView plugins directory (typically /plugins folder). Look for files related to RLE image format supportAffected if RLE parsing capability exists via plugins or built-in support
-
Inspect file association for .rle filesCheck Windows registry or system file associations to see if IrfanView is configured to open .rle files, or review recent file access logs for .rle file processingAffected if IrfanView is configured as a handler for .rle files or has recently processed .rle files
The system is affected if IrfanView 4.44 (32-bit) is installed with RLE format support enabled and users process .rle files with it.

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 dataDo not open untrusted or unverified .rle files in IrfanView until a patched version is available. Consider using application isolation or sandboxing for viewing legacy image formats.
