A use of uninitialized memory vulnerability in the pybddisasm Python bindings may disclose process memory when instruction decoding fails. The nd_decode, nd_decode_ex, nd_decode_ex2, and nd_decode_with_context functions may return an INSTRUX object whose contents have not been initialized after an unsuccessful decoding operation, including failures caused by invalid parameters. Accessing members of the returned object may expose residual process memory. Exploitation requires an application to access and expose the returned object contents after a decoding failure. The pybddisasm package is no longer maintained.
