their native formats and transforms them into a tree. Configuration changes
are made by manipulating this tree and saving it back into native config
files.

escaped strings. An attacker could send crafted strings that would cause
the application using augeas to copy past the end of a buffer, leading to a
crash or possible code execution. (CVE-2017-7555)
