A vulnerability was found in WebAssembly wabt 1.0.36 and classified as critical. This issue affects the function wabt::interp::(anonymous namespace)::BinaryReaderInterp::OnExport of the file wabt/src/interp/binary-reader-interp.cc of the component Malformed File Handler. The manipulation leads to heap-based buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue.
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.
