Bug #10988: [PATCH] Raise ArgumentError when string passed to String#crypt contains null
https://bugs.ruby-lang.org/issues/10988#change-53201
* Author: Jan Rusnacko
* Status: Closed
* Priority: Normal
* Assignee:
* ruby -v: 2.3.0dev
* Backport: 2.0.0: WONTFIX, 2.1: WONTFIX, 2.2: UNKNOWN
----------------------------------------
Currently String#crypt assumes that it is called on a password typed
by the user, specifically, that it does not contain null character.
When it does:
"abc\0def".crypt("pass") == "abc".crypt("pass")
=> true
This may not be desirable, and developers invoking crypt on strings
that potentially include null may expect different results. To
prevent security failures, this patch changes String#crypt to throw
ArgumentError when invoked on String that includes null character.
