Overview
Affected versions of this package are vulnerable to Buffer Underwrite (Buffer Underflow) via the DecodeImage function in coders/pict.c due to pointer arithmetic overflow. An attacker can cause memory corruption or execute arbitrary code by supplying a crafted PICT file with maximized row, column, and bytes-per-line values to bypass bounds checks and write controlled data below the heap buffer.
