GIMP PGM File Parsing Uninitialized Memory Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PGM files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28158.
Security readout for executives and security teams
Plain-English summary
CVE-2026-2044 is a high-severity GIMP flaw in PGM image parsing. A victim must open a malicious file or visit a malicious page, but successful exploitation could run attacker code as the current user.
Executive priority
Prioritize remediation for workstations and content-processing systems that handle external images. The business risk is code execution after user interaction, not a wormable network attack.
Technical view
The flaw is CWE-908: uninitialized memory use during PGM parsing in GIMP. The source bundle identifies GIMP 3.0.6 as affected and assigns CVSS 3.1 score 8.8 with high confidentiality, integrity, and availability impact.
Likely exposure
Primary exposure is endpoints or workflows using GIMP 3.0.6 to open PGM or untrusted image content. Red Hat advisories are referenced, so organizations should also check relevant Red Hat package status.
Exploitation context
The bundle reports remote code execution requiring user interaction. KEV is false, and the provided sources do not state active exploitation in the wild.
Researcher notes
ZDI attributes this to PGM parser uninitialized memory and references ZDI-CAN-28158. The bundle does not include exploit details or a named fixed GIMP version, so validation should stay source-based.
Mitigation direction
Apply vendor updates from GIMP/GNOME or Red Hat where applicable.
Avoid opening untrusted PGM files until remediation is confirmed.
Restrict GIMP use in automated pipelines handling external images.
Monitor vendor advisories for the fixed package or release details.
Validation and detection
Inventory systems with GIMP installed, especially version 3.0.6.
Check Red Hat advisory applicability for managed Linux fleets.
Confirm whether workflows ingest PGM files from external sources.
Verify users cannot open untrusted image attachments on vulnerable hosts.
