Claim

ASCII Armor makes it impossible to insert certain data.

General

ASCII Armor is a exploit mitigation strategy at runtime. It makes sure to map addresses of libraries to memory addresses with leading null byte(s). Like this it becomes hard to abuse C's strcpy and similar behaving functions, because the null byte indicates this functions the termination of strings.

ASCII Armor fights trivial attacks overwriting a buffer using functions which terminate when a specified termination character is read.
