stack ¤

Helpers for finding address mappings which are used as a stack.

Generally not needed, except under qemu-user and for when binaries do things to remap the stack (e.g. pwnies' postit).

Functions:

• find –

  Returns a pwndbg.lib.memory.Page object which corresponds to given address stack

• find_upper_stack_boundary –
• get –

  For each running thread, return the known address range for its stack

• current –

  Returns the bounds for the stack for the current thread.

• is_executable –
• callstack –

  Return the address of the return address for the current frame.

Attributes:

• auto_explore –

auto_explore = add_param(
    "auto-explore-stack",
    "warn",
    "stack exploration; it may be really slow",
    param_class=PARAM_ENUM,
    enum_sequence=["warn", "yes", "no"],
)

find(address: int) -> Page | None

find_upper_stack_boundary(stack_ptr: int, max_pages: int = 1024) -> int

get() -> dict[int, Page]

current() -> Page | None

is_executable() -> bool

callstack() -> list[int]
