A stack-based buffer overflow in the find_green() function of dcraw through 9.28, as used in ufraw-batch and many other products, may allow a remote attacker to cause a control-flow hijack, denial-of-service, or unspecified other impact via a maliciously crafted raw photo file.

Security readout for executives and security teams

Plain-English summary

This flaw is in dcraw, software used to process RAW photo files. A malicious RAW image could crash a vulnerable processor or potentially hijack execution flow when parsed. Risk is highest where servers, pipelines, or desktop tools automatically process untrusted image uploads or email attachments.

Executive priority

Prioritize remediation for any internet-facing or automated media-processing workflow. For isolated desktop-only use, urgency is lower but still worth addressing through normal patching because the reported impact includes possible control-flow hijack.

Technical view

CVE-2018-19655 is a stack-based buffer overflow in dcraw through 9.28, specifically find_green(). The CVE states ufraw-batch and other products may use the vulnerable code. Reported impacts include control-flow hijack, denial of service, or unspecified effects from a crafted RAW photo file.

Likely exposure

Exposure is likely limited to systems that run dcraw through 9.28, ufraw-batch, or bundled dcraw-derived code against untrusted RAW photo files. The provided data does not enumerate all affected downstream products.

Exploitation context

The provided sources do not show active exploitation, and KEV is false. Exploitation requires getting a crafted RAW photo file processed by vulnerable software. The practical risk depends on whether image conversion runs automatically and whether it is isolated.

Researcher notes

Evidence is sparse in the provided bundle: no CVSS, CWE, complete affected-product list, exploit status, or fixed upstream version is included. The strongest statements are the CVE description and vendor-advisory references from Fedora and Debian bug reports.

Mitigation direction

  • Inventory dcraw, ufraw-batch, and tools that bundle dcraw-derived RAW parsers.
  • Check operating system and application vendor advisories for fixed packages.
  • Apply vendor updates where available, including relevant distribution security updates.
  • Avoid processing untrusted RAW files until affected tools are updated or isolated.
  • Run image conversion in a constrained, least-privilege environment.

Validation and detection

  • Confirm whether dcraw version 9.28 or earlier is installed or bundled.
  • Trace upload, email, and media workflows that process RAW photo files.
  • Verify vendor package advisories apply to deployed distributions and versions.
  • Confirm updated packages are installed after remediation.
  • Review logs for crashes in RAW image processing services.
