A vulnerability was found in WebAssembly wabt 1.0.36. It has been declared as critical. This vulnerability affects the function BinaryReaderInterp::GetReturnCallDropKeepCount of the file wabt/src/interp/binary-reader-interp.cc. The manipulation leads to heap-based buffer overflow. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.
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.
The product writes data past the end, or before the beginning, of the intended buffer.
