Heap-based buffer overflow in the WPG format reader in GraphicsMagick 1.3.25 and earlier allows remote attackers to have unspecified impact via a colormap with a large number of entries.
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.
