wasm3 NewCodePage memory leak

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.

wasm3 m3_exec.h op_CallIndirect memory corruption

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.

wasm3 m3_compile.c MarkSlotAllocated out-of-bounds write

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.
