2DescriptionNVD
A flaw was found in GIMP. A signed integer overflow vulnerability exists in the file-fli plugin when processing FLI image files. This occurs due to an incorrect calculation during memory allocation for image buffers, where the multiplication of image width and height can exceed the maximum integer value. A remote attacker could exploit this by tricking a user into opening a specially crafted FLI file, leading to the application crashing and resulting in a denial of service.
AnalysisAI
Signed integer overflow in GIMP's file-fli plugin causes application crashes when processing maliciously crafted FLI animation files, resulting in denial of service. The flaw affects GIMP as packaged on Red Hat Enterprise Linux 6 through 9, where incorrect multiplication of image width and height during buffer size calculation can overflow a signed integer, producing an invalid allocation. No public exploit code or active exploitation has been identified; impact is strictly limited to availability, with no confidentiality or integrity consequences.
Technical ContextAI
GIMP's file-fli plugin handles the legacy FLI and FLC animation formats, originally developed by Autodesk. The root cause is CWE-190 (Integer Overflow or Wraparound): when computing the size of an image buffer, the product of image width and height is held in a signed integer type, and sufficiently large crafted dimension values cause the result to wrap around into a negative or truncated value, yielding an undersized or invalid memory allocation. The CPE strings confirm the affected surface as GIMP shipped within Red Hat Enterprise Linux 6-9 (cpe:2.3:a:red_hat:red_hat_enterprise_linux_6 through _9). Upstream tracking is via the GNOME project at gitlab.gnome.org/GNOME/gimp/-/work_items/16492. No upstream GIMP CPE is enumerated in the provided data, so other distributions carrying the same plugin code may also be affected.
RemediationAI
No patched GIMP version has been confirmed in the available data. Monitor the Red Hat security advisory at https://access.redhat.com/security/cve/CVE-2026-59088 and Red Hat Bugzilla entry https://bugzilla.redhat.com/show_bug.cgi?id=2496582 for errata packages targeting RHEL 6-9; apply them when released. As an interim compensating control, administrators can configure email gateway content filters to strip or quarantine .fli and .flc attachments, eliminating the most common delivery vector with minimal operational impact. Alternatively, removing or disabling the file-fli plugin from the GIMP plugin directory eliminates the vulnerable code path entirely, at the cost of losing FLI/FLC animation support - an acceptable trade-off given the format's limited modern use. Users should also be advised not to open FLI/FLC files received from untrusted sources. Track upstream patch progress at https://gitlab.gnome.org/GNOME/gimp/-/work_items/16492.
