A Denial of Service vulnerability exits in Binaryen 103 due to an assertion abort in wasm::handleunreachable.

An issue in wasm2c 1.0.32, wasm2wat 1.0.32, wasm-decompile 1.0.32, and wasm-validate 1.0.32 allows attackers to cause a Denial of Service (DoS) via running a crafted binary.

WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. Prior to version 2.4.4, an out-of-bounds array access issue exists in WAMR's fast interpreter mode during WASM bytecode loading. When framerefbottom and frameoffsetbottom arrays are at capacity and a GETGLOBAL(I32) opcode is encountered, framerefbottom is expanded but frameoffsetbottom may not be. If this is immediately followed by an if opcode that triggers preservelocalforblock, the function traverses arrays using stackcellnum as the upper bound, causing out-of-bounds access to frameoffsetbottom since it wasn't expanded to match the increased stackcellnum. This issue has been patched in version 2.4.4.

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.

wasm-interp v1.0.29 was discovered to contain an out-of-bounds read via the component OnReturnCallIndirectExpr->GetReturnCallDropKeepCount.

wasm-interp v1.0.29 was discovered to contain an out-of-bounds read via the component OnReturnCallExpr->GetReturnCallDropKeepCount.

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 demonstrated by wasm-opt.

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 demonstrated by wasm-opt.

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/simpleast.h. A crafted input can cause segmentation faults, leading to denial-of-service, as demonstrated by wasm2js.

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.

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.

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 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 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.

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.

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.

Heap-buffer-overflow in /src/wasm/wasm-binary.cpp in wasm::WasmBinaryBuilder::visitBlock(wasm::Block) in Binaryen 1.38.26. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm-opt.

A NULL pointer dereference was discovered in SExpressionWasmBuilder::makeBlock in wasm/wasm-s-parser.c in Binaryen 1.38.26. A crafted wasm input can cause a segmentation fault, leading to denial-of-service, as demonstrated by wasm-as.
