# `executable-stack-in-shared-library`

The listed shared library declares the stack as executable.

Executable stack is usually an error as it is only needed if the code contains GCC trampolines or similar constructs which uses code on the stack. One possible source for false positives are object files built from assembler files which don't define a proper .note.GNU-stack section.

To see the permissions on the stack, run `readelf -l` on the shared library and look for the program header of type GNU_STACK. In the flag column, there should not be an E flag set.

This tag is currently not emitted on MIPS architectures.

Severity: | `warning`
Experimental: | `false`
Renamed from: | `shlib-with-executable-stack`
