## Description

Vim is a greatly improved version of the good old UNIX editor Vi. Vimallows to redirect screen messages using the `:redir` ex command toregister, variables and files. It also allows to show the contents ofregisters using the `:registers` or `:display` ex command. When redirectingthe output of `:display` to a register, Vim will free the register contentbefore storing the new content in the register. Now when redirecting the`:display` command to a register that is being displayed, Vim will free thecontent while shortly afterwards trying to access it, which leads to ause-after-free. Vim pre 9.1.1115 checks in the ex_display() function, thatit does not try to redirect to a register while displaying this register atthe same time. However this check is not complete, and so Vim does notcheck the `+` and `*` registers (which typically donate the X11/clipboardregisters, and when a clipboard connection is not possible will fall backto use register 0 instead. In Patch 9.1.1115 Vim will therefore skipoutputting to register zero when trying to redirect to the clipboardregisters `*` or `+`. Users are advised to upgrade. There are no knownworkarounds for this vulnerability.
