A vulnerability has been found in wasm3 up to 0.5.0. The affected element is the function NewCodePage. The manipulation leads to memory leak. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. Unfortunately, the project has no active maintainer at the moment.

A vulnerability was detected in wasm3 up to 0.5.0. Impacted is the function op_SetSlot_i32/op_CallIndirect of the file m3_exec.h. Performing a manipulation results in memory corruption. The attack needs to be approached locally. The exploit is now public and may be used. Unfortunately, the project has no active maintainer at the moment.

A vulnerability has been found in wasm3 0.5.0 and classified as problematic. This vulnerability affects the function MarkSlotAllocated of the file source/m3_compile.c. The manipulation leads to out-of-bounds write. An attack has to be approached locally. The exploit has been disclosed to the public and may be used.

wasm3 139076a contains a Use-After-Free in ForEachModule.

wasm3 139076a contains memory leaks in Read_utf8.

wasm3 139076a suffers from Invalid Memory Read, leading to DoS and potential Code Execution.

wasm3 139076a is vulnerable to Denial of Service (DoS).

wasm3 v0.5.0 was discovered to contain an out-of-bound memory read which leads to segmentation fault via the function "main" in wasm3/platforms/app/main.c.

wasm3 v0.5.0 was discovered to contain a global buffer overflow which leads to segmentation fault via the function "PreserveRegisterIfOccupied" in wasm3/source/m3_compile.c.

wasm3 v0.5.0 was discovered to contain a heap buffer overflow which leads to segmentation fault via the function "DeallocateSlot" in wasm3/source/m3_compile.c.

wasm3 commit 7890a2097569fde845881e0b352d813573e371f9 was discovered to contain a segmentation fault via the component op_CallIndirect at /m3_exec.h.
