Last modified
CVE-2019-7154 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. The main function in tools/wasm2js.cpp in Binaryen 1.38.22 has a heap-based buffer overflow because Emscripten is misused, triggering an error in cashew::JSPrinter::printAst() in emscripten-optimizer/simple_ast.h. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm2js.. EPSS estimates a 1.12% chance of exploitation in the next 30 days.
