Description
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.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. A reference of the record is tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
