Other communication channels can also be used to inform users about the security release. diff --git a/tests/regression/ba-issues/build_wamr.sh b/tests/regression/ba-issues/build_wamr.sh index 9f2b3c716f..233f7bad8f 100755 --- a/tests/regression/ba-issues/build_wamr.sh +++ b/tests/regression/ba-issues/build_wamr.sh @@ -66,4 +66,8 @@ build_iwasm "-DWAMR_BUILD_BRANCH_HINTS=1" "default-branch-hints-enabled" # build default iwasm for testing tail call with fast-interp build_iwasm "-DWAMR_BUILD_REF_TYPES=1 -DWAMR_BUILD_FAST_INTERP=1 -DWAMR_BUILD_TAIL_CALL=1 -DWAMR_BUILD_LIBC_WASI=0" "default-tail-call-wasi-disabled" +# build classic-interp iwasm with ASAN and hardware bounds checks disabled +# for poll_oneoff host memory safety regressions +build_iwasm "-DWAMR_BUILD_REF_TYPES=1 -DWAMR_BUILD_FAST_INTERP=0 -DWAMR_BUILD_AOT=0 -DWAMR_BUILD_JIT=0 -DWAMR_BUILD_FAST_JIT=0 -DWAMR_BUILD_SIMD=0 -DWAMR_DISABLE_HW_BOUND_CHECK=1" "poll-oneoff-asan" + # TODO: add more version of iwasm, for example, sgx version diff --git a/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wasm b/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wasm new file mode 100644 index 0000000000..ec56c43f3d Binary files /dev/null and b/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wasm differ diff --git a/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wat b/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wat new file mode 100644 index 0000000000..2121e0b64e --- /dev/null +++ b/tests/regression/ba-issues/issues/issue-980004/poll_oneoff_out_of_bounds_write.wat @@ -0,0 +1,38 @@ +(module + (import "wasi_snapshot_preview1" "poll_oneoff" + (func $poll_oneoff (param i32 i32 i32 i32) (result i32))) + (import "wasi_snapshot_preview1" "proc_exit" + (func $proc_exit (param i32))) + (memory (export "memory") 1) + (func (export "_start") + ;;
