# CVE-2026-96545: Gimp: gimp: out-of-bounds heap read in the 4bpp tim image loader

Status: published. Published: 2026-09-23. Updated: 2026-11-06.

An out-of-bounds heap read flaw was found in GIMP's TIM image loader. When a user opens a crafted 4bpp TIM image that causes promotion to an RGBA layer, the file-tim plug-in allocates an undersized row buffer but processes it using the larger RGBA row size. This can copy adjacent heap contents into the decoded image and may crash the plug-in.

## Remediation

- workaround: Do not open TIM image files from untrusted sources. No application-level mitigation that preserves processing of untrusted TIM files is known. (source: CNA: redhat)
