Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
