GIMP SGI File Parsing Integer 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 SGI files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29396.
AnalysisAI
Remote code execution is possible in GIMP 3.2.2 through a maliciously crafted SGI image file, exploiting an integer overflow in the application's SGI file parser. An unauthenticated remote attacker can deliver the file via email or web and, upon the victim opening it, execute arbitrary code within the GIMP process context with the privileges of the logged-in user. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to actively open a crafted SGI raster image file in GIMP 3.2.2 on any supported platform (Windows, Linux, macOS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H accurately reflects the attack model: 'local' here means a file-open action by the victim rather than physical machine access, no attacker privileges are required, but successful exploitation is gated on user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious SGI image file with manipulated header fields designed to trigger an integer overflow in GIMP's parser, then delivers it via a phishing email or a drive-by download page. The victim opens the file in GIMP 3.2.2, the parser overflows during dimension or channel calculation, and the resulting heap corruption enables the attacker to redirect execution to shellcode running as the victim's local user account. … |
| Remediation | The primary fix is an upstream patch commit available at https://gitlab.gnome.org/GNOME/gimp/-/commit/76531da9732f38566e5fd8f8f80c837158511ae5, which addresses the integer overflow in the SGI parser. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Alert all GIMP users to avoid opening SGI image files (.sgi, .bw, .rgb extensions) from untrusted sources and inventory all GIMP 3.2.2 installations across the organization. …
