Name of the Vulnerable Software and Affected Versions Binaryen version 1.38.22

Description A NULL pointer dereference issue was found in the wasm::Module::getFunctionOrNull function in wasm/wasm.cpp. This can be triggered by a crafted input, resulting in segmentation faults and leading to denial-of-service.

Recommendations For Binaryen version 1.38.22, consider avoiding the use of the wasm::Module::getFunctionOrNull function until a patch is available. As a temporary workaround, restrict the input to prevent crafted data from causing segmentation faults. At the moment, there is no information about a newer version that contains a fix for this issue.
