+Subject: [PATCH] Fix CVE-2023-24816 by removing legacy code.
+
+Remove legacy code that might trigger a CVE.
+
+Currently set_term_title is only called with (semi-)trusted input that
+contain the current working directory of the current IPython session. If
+an attacker can control directory names, and manage to get a user cd
+into this directory the attacker can execute arbitrary commands
+contained in the folder names.
+
+Example:
+
+ - On a windows machine where python is built without _ctypes, create
+ a folder called && echo "pwn" > pwn.txt. This can be done by for
+ example cloning a git repository.
+ - call toggled_set_term_title(True), (or have the preference to
+ true)
+ - Open IPython and cd into this directory.
+ - the folder now contain a pwn.txt, with pwn as content, despite the
+ user not asking for any code execution.
+
+Workaround:
+
+ Set the configuration option
+ c.TerminalInteractiveShell.term_title_format='IPython' (or to any
+ other fixed, safe string).
+
+CVE: CVE-2023-24816
+Upstream-Status: Backport [https://github.com/ipython/ipython/commit/385d69325319a5972ee9b5983638e3617f21cb1f]
