A vulnerability was detected in WebAssembly Binaryen up to 117. This issue affects the function IRBuilder::makeBrOn of the file src/wasm/wasm-ir-builder.cpp of the component BrOn Parser. Performing a manipulation results in reachable assertion. The attack needs to be approached l...
A vulnerability was identified in WebAssembly Binaryen up to 125. This affects the function IRBuilder::makeLocalGet/IRBuilder::makeLocalSet/IRBuilder::makeLocalTee of the file src/wasm/wasm-ir-builder.cpp of the component IRBuilder. Such manipulation of the argument Index leads t...
A vulnerability was determined in WebAssembly Binaryen up to 125. Affected by this issue is the function WasmBinaryReader::readExport of the file src/wasm/wasm-binary.cpp. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host....
An issue was discovered in Binaryen 1.38.32. Two visitors in ir/ExpressionManipulator.cpp can lead to a NULL pointer dereference in wasm::LocalSet::finalize in wasm/wasm.cpp. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm2js.
An issue was discovered in Binaryen 1.38.32. Missing validation rules in asmjs/asmangle.cpp can lead to an Assertion Failure at wasm/wasm.cpp in wasm::asmangle. A crafted input can cause denial-of-service, as demonstrated by wasm2js.
wasm::WasmBinaryBuilder::readUserSection in wasm-binary.cpp in Binaryen 1.38.22 triggers an attempt at excessive memory allocation, as demonstrated by wasm-merge and wasm-opt.
In Binaryen 1.38.22, there is a use-after-free problem in wasm::WasmBinaryBuilder::visitCall in wasm-binary.cpp. Remote attackers could leverage this vulnerability to cause a denial-of-service via a wasm file, as demonstrated by wasm-merge.
A NULL pointer dereference was discovered in wasm::SExpressionWasmBuilder::parseExpression in wasm-s-parser.cpp in Binaryen 1.38.22. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm-as.
A heap-based buffer over-read was discovered in wasm::SExpressionParser::skipWhitespace() in wasm-s-parser.cpp in Binaryen 1.38.22. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm2js.
A heap-based buffer over-read was discovered in wasm::WasmBinaryBuilder::visitCall in wasm-binary.cpp in Binaryen 1.38.22. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm-merge.
An assertion failure was discovered in wasm::WasmBinaryBuilder::getType() in wasm-binary.cpp in Binaryen 1.38.22. This allows remote attackers to cause a denial of service (failed assertion and crash) via a crafted wasm file.
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-o...
A NULL pointer dereference was discovered in wasm::WasmBinaryBuilder::processFunctions() in wasm/wasm-binary.cpp (when calling wasm::WasmBinaryBuilder::getFunctionIndexName) in Binaryen 1.38.22. A crafted input can cause segmentation faults, leading to denial-of-service, as demon...
A heap-based buffer over-read was discovered in wasm::WasmBinaryBuilder::processFunctions() in wasm/wasm-binary.cpp (when calling wasm::WasmBinaryBuilder::getFunctionIndexName) in Binaryen 1.38.22. A crafted input can cause segmentation faults, leading to denial-of-service, as de...
A NULL pointer dereference was discovered in wasm::Module::getFunctionOrNull in wasm/wasm.cpp in Binaryen 1.38.22. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm-opt.
