When pasting characters into several terminal emulators, control characters are allowed. This turns to be a security problem, due to the fact that when pasting these characters into terminal text editors, such as vi/vim, emacs, nano, etc., remote code execution is possible. This is supposed to be fixed in recent versions of VTE [3], which means VTE-based terminal emulators should be safe, but the problem is that most distros are shipping older versions and remain vulnerable. Here's a list of terminal emulators I tested this where it worked. Some came by default in my distro (debian), others were installed via apt-get. This should also work on other distros:
[...]
urxvt
[...]
Please, update VTE and check if the below still works. For the others that aren't based on VTE, CVEs should be assigned to each of them. Can someone help me figure out which ones are based on VTE and those that aren't?
As far as I can see, urxvt (aka rxvt-unicode) does not use vte. -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup. To reply privately _only_ on Usenet and on broken lists which rewrite From, fetch the TXT record for no-use.mooo.com.
