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-28266.

AnalysisAI

Arbitrary code execution in GIMP results from a heap-based buffer overflow in the HDR file parser, where attacker-controlled length data is copied into an undersized heap buffer without bounds validation. Any user who opens a maliciously crafted HDR image (or visits a page that delivers one) can be exploited, with code running in the context of the GIMP process. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the victim to open or load a specially crafted HDR (Radiance/RGBE) image file in GIMP - the malicious data must traverse the GEGL HDR parsing path. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.0 vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 7.8) describes a local, file-open-driven flaw with high impact to confidentiality, integrity, and availability but requiring user interaction - consistent with a client-side document-parsing bug rather than a remotely reachable service. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a malicious HDR image and delivers it via a phishing email attachment or a web page that auto-downloads it, then lures a victim into opening the file in GIMP. Parsing the file overflows a heap buffer and lets the attacker execute code as the victim's user account. …
Remediation Upstream fix available (PR/commit); released patched version not independently confirmed - the correction has been merged in GEGL via merge request 241 (https://gitlab.gnome.org/GNOME/gegl/-/merge_requests/241), so upgrade GIMP and its bundled GEGL to a build that incorporates that merge once your distribution publishes it, and consult ZDI-26-282 (https://www.zerodayinitiative.com/advisories/ZDI-26-282/) for tracking. … Detailed patch versions, workarounds, and compensating controls in full report.
