WebAssembly wabt wasm-decompile VarName out-of-bounds
Summary
A security vulnerability has been detected in WebAssembly wabt up to 1.0.39. This issue affects the function wabt::Decompiler::VarName of the file /src/repro/wabt/bin/wasm-decompile of the component wasm-decompile. Such manipulation leads to out-of-bounds read. Local access is required to approach this attack. The exploit has been disclosed publicly and may be used. Unfortunately, the project has no active maintainer at the moment. In a reply to the issue report somebody recommended to the researcher to provide a PR himself.

Title
WebAssembly wabt binary-reader-interp.cc GetFuncOffset use after free
Summary
A vulnerability was found in WebAssembly wabt up to 1.0.37. It has been declared as problematic. Affected by this vulnerability is the function GetFuncOffset of the file src/interp/binary-reader-interp.cc. The manipulation leads to use after free. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. A similar issue reported during the same timeframe was disputed by the code maintainer because it might not affect "real world wasm programs". Therefore, this entry might get disputed as well in the future.

Title
WebAssembly wabt binary-reader-interp.cc GetFuncOffset use after free
Summary
A vulnerability was found in WebAssembly wabt up to 1.0.37. It has been declared as problematic. Affected by this vulnerability is the function GetFuncOffset of the file src/interp/binary-reader-interp.cc. The manipulation leads to use after free. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. A similar issue reported during the same timeframe was disputed by the code maintainer because it might not affect "real world wasm programs". Therefore, this entry might get disputed as well in the future.
