Technical details
A null pointer dereference vulnerability exists in the C++ attribute parsing code when processing an unknown-type attribute with dataSize set to zero. The OpaqueAttribute constructor passes a null pointer directly to memcpy() without validation, resulting in undefined behavior and process termination. The vulnerability requires parsing a specially crafted EXR file and is fixed by skipping the memcpy call when size is zero.
