CVE-2026-96545
Gimp: gimp: out-of-bounds heap read in the 4bpp tim image loader
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.
Fixes and workarounds
Workaround
Do not open TIM image files from untrusted sources. No application-level mitigation that preserves processing of untrusted TIM files is known.
