CVE-2026-92183 GIMP CVE debrief

A GIMP APNG file parsing stack-based buffer overflow remote code execution vulnerability exists. The vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability. The specific flaw exists within the parsing of APNG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. This vulnerability is a significant concern for defenders, as it can lead to potential remote code execution on affected GIMP The issue

Who should care

Defenders responsible for GIMP installations, especially in environments where users may open or interact with APNG files from untrusted sources, should assess exposure and prioritize patching.

Why it matters

Defenders should prioritize patching GIMP installations to prevent potential remote code execution. User interaction is required to exploit this vulnerability, but it can have significant consequences if not addressed.

  • Potential remote code execution on affected GIMP installations
  • Requires user interaction to exploit
  • Patching GIMP installations is crucial to prevent exploitation

Technical summary

The vulnerability exists within the parsing of APNG files in GIMP. An attacker can leverage this vulnerability to execute code in the context of the current process. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. This vulnerability is a significant concern for defenders, as it can lead to potential remote code execution on affected GIMP installations. User interaction is required to exploit this vulnerability, but it can have significant consequences if not addressed. The vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP.

Defensive priority

Defenders should prioritize patching GIMP installations, especially in environments where users may open or interact with APNG files from untrusted sources.

Recommended defensive actions

  • Patch GIMP installations to the latest version
  • Restrict user interaction with APNG files from untrusted sources
  • Monitor GIMP installations for suspicious activity
  • Implement additional security measures such as intrusion detection systems
  • Conduct regular vulnerability assessments
  • Review and update incident response plans
  • Ensure proper configuration and hardening of GIMP installations

Evidence notes

The vulnerability is caused by a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer when parsing APNG files.
