Security readout for executives and security teams

Plain-English summary

CVE-2023-47995 is a denial-of-service issue in FreeImage 3.18.0. A crafted image could trigger excessive memory allocation and make an affected application unavailable. The sources do not indicate data theft or code execution.

Executive priority

Handle as a moderate availability risk. Prioritize faster if FreeImage handles internet-supplied images or supports customer-facing upload workflows. It is not an emergency based on the supplied evidence.

Technical view

The issue is reported in BitmapAccess.cpp::FreeImage_AllocateBitmap, involving allocation with an excessive size value. CVSS 3.1 is 6.5: network reachable, low complexity, no privileges, user interaction required, and high availability impact only.

Likely exposure

Exposure is most likely where FreeImage 3.18.0 processes untrusted image files, such as upload, thumbnailing, conversion, or document-ingestion workflows. The provided affected-product metadata is incomplete, so confirm through SBOMs and package inventories.

Exploitation context

The CVE is not listed as KEV, and the provided sources do not show active exploitation. A public PoC reference is listed, so treat untrusted image parsing paths as higher priority without assuming exploitation in the wild.

Researcher notes

The source bundle names FreeImage 3.18.0 but has incomplete affected CPE metadata. The weakness is labeled CWE-120, though the described impact is excessive allocation leading to denial of service.

Mitigation direction

  • Inventory FreeImage usage in applications, containers, and operating-system packages.
  • Apply vendor or distribution updates where available, including relevant Fedora advisories.
  • Reduce exposure of untrusted image processing until patched.
  • Run image parsing in constrained workers with memory and timeout limits.
  • Check upstream and vendor guidance for definitive fixed versions.

Validation and detection

  • Confirm whether FreeImage 3.18.0 exists in SBOMs or package inventories.
  • Map all routes and jobs that process user-supplied images.
  • Compare installed Fedora packages against the referenced Fedora advisories.
  • Verify resource limits around image conversion and thumbnail generation.
  • Use safe lab regression inputs to confirm failures are contained.
