LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3724, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 33aee127.

Security readout for executives and security teams

Plain-English summary

This issue affects LibTIFF’s tiffcrop tool. A crafted TIFF file can trigger an out-of-bounds write and cause denial of service. The available sources name LibTIFF 4.4.0 and earlier, with a source fix commit identified. There is no KEV listing or cited evidence of active exploitation.

Executive priority

Treat as a moderate-priority availability risk. Prioritize systems that process external TIFF files automatically or support business-critical image workflows. Routine patching is appropriate unless tiffcrop handles untrusted content in production.

Technical view

CVE-2023-0802 is a CWE-787 out-of-bounds write in tools/tiffcrop.c around line 3724 in LibTIFF <=4.4.0. CVSS 3.1 is 6.8, with local attack vector, low complexity, no privileges, no confidentiality impact, low integrity impact, and high availability impact.

Likely exposure

Exposure is most likely where LibTIFF <=4.4.0 or the tiffcrop utility processes untrusted or user-supplied TIFF files. Risk may also exist through downstream operating system packages or products that bundle affected LibTIFF versions, as reflected by Debian, Gentoo, and NetApp advisories.

Exploitation context

The sources describe denial of service through a crafted TIFF file. The bundle marks KEV as false, and no provided source states active exploitation. Evidence does not support claiming widespread exploitation or remote code execution.

Researcher notes

The provided data supports an out-of-bounds write in tiffcrop with denial-of-service impact and a named upstream fix. It does not establish active exploitation, exploit maturity, or broader impact beyond affected LibTIFF versions and downstream advisories.

Mitigation direction

  • Update LibTIFF packages using your operating system or vendor advisory channel.
  • For source builds, verify the fix includes commit 33aee127.
  • Limit tiffcrop processing of untrusted TIFF files until patched.
  • Track Debian, Gentoo, NetApp, or other vendor advisories for affected downstream products.

Validation and detection

  • Inventory systems and containers for LibTIFF or tiffcrop versions <=4.4.0.
  • Check SBOMs and package manifests for bundled LibTIFF dependencies.
  • Confirm patched builds include the referenced upstream fix commit.
  • Identify workflows that automatically process user-supplied TIFF files with tiffcrop.
  • Verify vendor package versions against Debian, Gentoo, or product advisories.
