Bug Description
Because of a missing stack marking in arm-mem repository (libarmmem.so), all binaries loading this library have their stack marked as executable and ignore a compiled NX option.
The fix for this bug and a detailed description has been pushed to the original arm-mem repository: https:/
As a short summary:
- libarmmem.so is missing an important stack marking (to make the stack non executable)
- loading this shared lib will result in the stack marked as RWX, ignoring NX
- libarmmem.so is loaded in nearly all binaries, disabling NX system wide
