DescriptionCVE.org

GIMP HDR File Parsing Heap-based Buffer Overflow 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 HDR files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28618.

AnalysisAI

Arbitrary code execution in GIMP via malicious HDR (High Dynamic Range) image files allows attackers to run code in the context of the user opening the file. The flaw is a heap-based buffer overflow (CWE-122) in the HDR parser, requiring the victim to open a crafted file or visit a malicious page that delivers one. No public exploit identified at time of analysis, but the vulnerability was reported through ZDI (ZDI-CAN-28618) indicating verified researcher analysis.

Technical ContextAI

GIMP (GNU Image Manipulation Program) is a widely deployed open-source raster graphics editor. The vulnerability resides in GIMP's HDR (Radiance HDR / .hdr) file format parser, which is implemented in the GEGL (Generic Graphics Library) image processing framework - confirmed by the upstream advisory pointing to gitlab.gnome.org/GNOME/gegl issue #450. CWE-122 (Heap-based Buffer Overflow) identifies the root cause: the parser copies attacker-controlled data from the HDR file into a heap allocation without first validating that the source length fits the destination buffer, enabling heap corruption that can be steered into arbitrary code execution.

RemediationAI

No vendor-released patch identified at time of analysis - the GEGL upstream tracker (https://gitlab.gnome.org/GNOME/gegl/-/issues/450) is the authoritative location to monitor for a fixed GEGL release and corresponding GIMP version, and the ZDI advisory at https://www.zerodayinitiative.com/advisories/ZDI-26-214/ should be checked for vendor coordination updates. Until a patched build is available, the most effective compensating control is to refuse to open .hdr / Radiance HDR files from untrusted sources; organizations can enforce this by stripping or blocking the .hdr MIME type and extension at email gateways and web proxies (side effect: legitimate HDR workflows for VFX/3D/photography teams break and must be whitelisted). Where GIMP is deployed on multi-user systems, running it under a restricted user account or inside a sandbox such as Flatpak's default confinement, Firejail, or bubblewrap limits the blast radius of successful exploitation to the sandbox boundary rather than the user's full session.
