2DescriptionCVE.org
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.
AnalysisAI
Integer overflow in GIMP's PlayStation TIM image loader crashes the plug-in when processing a maliciously crafted TIM file, resulting in denial of service. The flaw affects GIMP as packaged on Red Hat Enterprise Linux 6 through 9, where the TIM loader multiplies two 16-bit unsigned short values (num_colors × num_cluts) without bounds checking, producing a 32-bit overflow that corrupts CLUT size calculation and triggers an abort. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to actively open a specially crafted PlayStation TIM image file within GIMP - the GIMP TIM loader plug-in must be present and enabled (default on RHEL GIMP packages). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is moderate-to-low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a PlayStation TIM image file with num_colors and num_cluts values chosen to trigger the 16-bit multiplication overflow - for example, 256 × 257 = 65,792, which truncates when stored in a 16-bit result - causing GIMP to allocate an undersized CLUT buffer. The attacker delivers this file to a target user via email attachment, shared drive, or web download, and persuades them to open it in GIMP. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the GNOME GitLab reference (https://gitlab.gnome.org/GNOME/gimp/-/work_items/16493) is a work item, not a closed merge request or tagged release, and no fixed version number appears in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
