Lifecycle Timeline
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. No public exploit code has been identified at time of analysis, and exploitation requires user interaction to open a crafted file, limiting real-world impact to targeted social engineering scenarios.
Technical ContextAI
The PlayStation TIM (Texture Image Map) format uses a Color Look-Up Table (CLUT) structure where num_colors and num_cluts are both 16-bit unsigned shorts (maximum value 65,535 each). Multiplying two uint16 values without promoting to a wider integer type before the multiplication yields CWE-190 (Integer Overflow or Wraparound): 65,535 × 65,535 ≈ 4.29 billion, which overflows a 32-bit signed integer. The resulting undercount causes GIMP to allocate insufficient memory for the CLUT buffer, leading to undefined behavior and plug-in abort. Affected CPE strings confirm the vulnerability exists in the GIMP packages shipped with Red Hat Enterprise Linux 6 (cpe:2.3:a:red_hat:red_hat_enterprise_linux_6), RHEL 7, RHEL 8, and RHEL 9. The root cause class (CWE-190) is a classic arithmetic overflow in a size computation - a well-understood but persistently common defect in image-format parsers that handle attacker-supplied dimensional values.
RemediationAI
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. Organizations running GIMP on RHEL 6-9 should monitor https://access.redhat.com/security/cve/CVE-2026-59089 for Red Hat errata updates and apply them as soon as they are released. As a compensating control, administrators can restrict or remove access to GIMP's file-type plug-ins directory to disable the TIM loader specifically, though this will break all PlayStation TIM image support and may affect other plug-ins if the directory is shared. An alternative is to configure file-type associations to warn users before opening lesser-known image formats. Given that exploitation requires user interaction, security awareness guidance cautioning users not to open TIM files from untrusted sources provides meaningful risk reduction with no operational downside.
