probeleak

Description

Pointer scan for possible offset leaks. Examples: probeleak $rsp 0x64 - leaks 0x64 bytes starting at stack pointer and search for valid pointers probeleak $rsp 0x64 --max-dist 0x10 - as above, but pointers may point 0x10 bytes outside of memory page probeleak $rsp 0x64 --point-to libc --max-ptrs 1 --flags rwx - leaks 0x64 bytes starting at stack pointer and search for one valid pointer which points to a libc rwx page

Usage:

usage: probeleak [-h] [--max-distance MAX_DISTANCE] [--point-to POINT_TO] [--max-ptrs MAX_PTRS] [--flags FLAGS] [address] [count]

Positional Arguments

Positional Argument	Help
address	Leak memory address (default: %(default)s)
count	Leak size in bytes (default: %(default)s)

Optional Arguments

Short	Long	Default	Help
-h	--help		show this help message and exit
	--max-distance	0	Max acceptable distance between memory page boundary and leaked pointer (default: %(default)s)
	--point-to	None	Mapping name of the page that you want the pointers point to
	--max-ptrs	0	Stop search after find n pointers, default 0 (default: %(default)s)
	--flags	None	flags of the page that you want the pointers point to. [e.g. rwx]
