[tor/master] channel: Fix use after free in channel_do_open_actions()
by nickm＠torproject.org 24 Mar '21

commit 9ca2394d6b51242bb5cf380757be5869d2a44c3c Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Mar 23 09:19:41 2021 -0400 channel: Fix use after free in channel_do_open_actions() Fortunately, our tor_free() is setting the variable to NULL after so we were in a situation where NULL was always used instead of the transport name. This first appeared in 894ff2dc8422cb86312c512698acd76476224f87 and results in basically no bridge with a transport being able to use DoS defenses.
