CVE-2018-3922: A memory corruption vulnerability exists in the ANI-parsing functionality of Computerinsel Photoline 20.54.

A memory corruption vulnerability exists in the ANI-parsing functionality of Computerinsel Photoline 20.54. A specially crafted ANI image processed via the application can lead to a stack overflow, overwriting arbitrary data. An attacker can deliver an ANI image to trigger this vulnerability and gain code execution.

Security readout for executives and security teams

Plain-English summary

CVE-2018-3922 is a high-severity flaw in Computerinsel Photoline 20.54 for OS X. A malicious ANI image can corrupt memory when opened or processed, potentially letting an attacker run code on the user’s machine. The business risk is highest where staff open untrusted graphics files.

Executive priority

Prioritize if Photoline 20.54 is used in creative, marketing, or intake workflows that handle external image files. For organizations without this software or ANI file handling, urgency is lower but inventory confirmation is still warranted.

Technical view

The vulnerability is in Photoline’s ANI parsing functionality. The CVE describes a stack overflow that can overwrite arbitrary data and lead to code execution. The CVSS 3.0 score is 8.8 with network delivery, low complexity, no privileges required, and required user interaction.

Likely exposure

Exposure appears limited to environments running Computerinsel Photoline 20.54 for OS X, especially users who receive or process ANI image files from untrusted sources. The provided sources do not identify other affected products or versions.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires delivery of a crafted ANI image and user interaction through processing the file in the affected application.

Researcher notes

Evidence is specific to ANI parsing in Computerinsel Photoline 20.54 for OS X. The source bundle supports code-execution impact but does not provide KEV status, exploitation evidence, or a named patch. Avoid broadening affected versions without vendor confirmation.

Mitigation direction

  • Check Computerinsel guidance for a fixed Photoline release or supported upgrade path.
  • Remove or upgrade Photoline 20.54 for OS X where found.
  • Avoid opening ANI files from untrusted or unsolicited sources.
  • Filter or quarantine ANI attachments if the format is not business-required.

Validation and detection

  • Inventory macOS systems for Computerinsel Photoline 20.54.
  • Confirm whether users process ANI images from email, web, or external submissions.
  • Review endpoint telemetry for Photoline crashes after ANI file handling.
  • Track vendor advisories and Talos reporting for confirmed remediation details.
