tif_getimage.c in LibTIFF through 4.0.10, as used in GDAL through 3.0.1 and other products, has an integer overflow that potentially causes a heap-based buffer overflow via a crafted RGBA image, related to a "Negative-size-param" condition.

Security readout for executives and security teams

Plain-English summary

This vulnerability is a memory-safety flaw in LibTIFF image handling. A specially crafted RGBA TIFF image could trigger an integer overflow and possible heap buffer overflow when processed by LibTIFF, GDAL, or products embedding them. The sources show vendor security updates, but no KEV listing or active exploitation evidence.

Executive priority

Treat as a focused patching priority for image-processing and geospatial systems, not a broad emergency. The business risk is untrusted file handling in exposed workflows. Lack of KEV evidence lowers urgency, but memory corruption in common libraries warrants timely remediation.

Technical view

CVE-2019-17546 affects tif_getimage.c in LibTIFF through 4.0.10 and GDAL through 3.0.1. The issue is an integer overflow leading to a potential heap-based buffer overflow during crafted RGBA image processing, associated with a Negative-size-param condition identified through OSS-Fuzz and addressed by upstream commits and distribution advisories.

Likely exposure

Exposure is most likely in systems that ingest, preview, convert, scan, or analyze TIFF imagery using LibTIFF, GDAL, or downstream packages. Risk is higher where untrusted image files are accepted from users, email, uploads, archives, geospatial pipelines, or automated document-processing workflows.

Exploitation context

The provided sources do not show CISA KEV inclusion or confirmed active exploitation. Exploitation would require a crafted RGBA image reaching vulnerable image-processing code. The record does not provide CVSS, reliable impact detail, or evidence of public weaponization.

Researcher notes

The strongest evidence is the CVE description, OSS-Fuzz reference, upstream LibTIFF and GDAL commits, and Linux distribution advisories. The record lacks CVSS, CWE, and detailed exploitability analysis. Avoid assuming remote code execution unless a specific downstream advisory supports it.

Mitigation direction

  • Upgrade LibTIFF and GDAL packages using vendor security advisories.
  • Prioritize systems that process untrusted TIFF or geospatial image files.
  • Apply Debian, Fedora, Gentoo, or vendor package updates where applicable.
  • Check downstream product advisories for bundled LibTIFF or GDAL copies.
  • Restrict untrusted TIFF processing until affected components are updated.

Validation and detection

  • Inventory installed LibTIFF and GDAL versions across servers, containers, and appliances.
  • Confirm LibTIFF is newer than 4.0.10 or vendor-patched.
  • Confirm GDAL is newer than 3.0.1 or vendor-patched.
  • Review image ingestion paths for TIFF and RGBA processing.
  • Verify package updates against Debian, Fedora, Gentoo, or vendor advisories.
