An issue was discovered in WAVM before 2018-09-16. The loadModule function in Include/Inline/CLI.h lacks checking of the file length before a file magic comparison, allowing attackers to cause a Denial of Service (application crash caused by out-of-bounds read) by crafting a file that has fewer than 4 bytes.

An issue was discovered in WAVM before 2018-09-16. The run function in Programs/wavm/wavm.cpp does not check whether there is Emscripten memory to store the command-line arguments passed by the input WebAssembly file's main function, which allows attackers to cause a denial of service (application crash by NULL pointer dereference) or possibly have unspecified other impact by crafting certain WebAssembly files.
