An issue was discovered in icoutils 0.31.1. A buffer overflow was observed in the "decode_ne_resource_id" function in the "restable.c" source file. This is happening because the "len" parameter for memcpy is not checked for size and thus becomes a negative integer in the process, resulting in a failed memcpy. This affects wrestool.
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.
