AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
AV:L because exploitation requires local file opening; UI:R reflects mandatory victim interaction; PR:N as no credentials precede delivery; high C/I/A reflects full RCE in process context.

GIMP TIF 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 TIF files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29405.
AnalysisAI
Remote code execution in GIMP 3.2.2 is achievable via a specially crafted TIF image file that triggers an integer overflow in the application's TIFF parser, causing an undersized heap allocation and subsequent memory corruption. An attacker who convinces a user to open a malicious file or visit an attacker-controlled page that delivers such a file can execute arbitrary code with the privileges of the victim's user account. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to actively open a specially crafted TIF file in GIMP - confirmed affected at version 3.2.2. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.8 with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H accurately reflects a file-parsing RCE where the attack vector is local execution but no attacker privileges are required prior to delivery. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a TIFF image file with manipulated metadata integer fields designed to overflow during GIMP's buffer allocation calculation, resulting in a heap buffer smaller than the subsequent write operation. The file is delivered via a phishing email, a drive-by download link, or an attacker-controlled webpage, and the victim is socially engineered into opening it in GIMP. … |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all GIMP 3.2.2 deployments and communicate the vulnerability to design and content teams with guidance to avoid opening TIFF files from external or untrusted sources; implement file-handling restrictions blocking TIFF downloads and attachments from external email. …
