String#b: Don't depend on dependent string Registering a string that depend on a dependent string as fstring can lead to use-after-free. See c06ddfe and 3f95620 for details. The following script triggers use-after-free on trunk, 2.4.6, 2.5.5 and 2.6.3. Credits to @wanabe for using eval as a cross-version way of registering a fstring. ```ruby a = ('j' * 24).b.b eval('', binding, a) p a 4.times { GC.start } p a ``` - string.c (str_replace_shared_without_enc): when given a dependent string, depend on the root of the dependent string.

[Bug #15792] str_duplicate: Don't share with a frozen shared string This is a follow up for 3f9562015e651735bfc2fdd14e8f6963b673e22a. Before this commit, it was possible to create a shared string which shares with another shared string by passing a frozen shared string to `str_duplicate`. Such string looks like: ``` -------- ----------------- | root | ------ owns -----> | root's buffer | -------- ----------------- ^ ^ ^ ----------- | | | shared1 | ------ references ----- | ----------- | ^ | ----------- | | shared2 | ------ references --------- ----------- ``` This is bad news because `rb_fstring(shared2)` can make `shared1` independent, which severs the reference from `shared1` to `root`: ```c /* from fstr_update_callback() */ str = str_new_frozen(rb_cString, shared2); /* can return shared1 */ if (STR_SHARED_P(str)) { /* shared1 is also a shared string */ str_make_independent(str); /* no frozen check */ } ``` If `shared1` was the only reference to `root`, then `root` can be reclaimed by the GC, leaving `shared2` in a corrupted state: ``` ----------- -------------------- | shared1 | -------- owns --------> | shared1's buffer | ----------- -------------------- ^ | ----------- ------------------------- | shared2 | ------ references ----> | root's buffer (freed) | ----------- ------------------------- ``` Here is a reproduction script for the situation this commit fixes. ```ruby a = ('a' * 24).strip.freeze.strip -a p a 4.times { GC.start } p a ``` - string.c (str_duplicate): always share with the root string when the original is a shared string. - test_rb_str_dup.rb: specifically test `rb_str_dup` to make sure it does not try to share with a shared string.
