Описание
Vim is an open source, command line text editor. A use-after-free was found in Vim < 9.1.0764. When closing a buffer (visible in a window) a BufWinLeave auto command can cause an use-after-free if this auto command happens to re-open the same buffer in a new split window. Impact is low since the user must have intentionally set up such a strange auto command and run some buffer unload commands. However this may lead to a crash. This issue has been addressed in version 9.1.0764 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
A flaw was found in Vim. When closing a buffer visible in a window, a BufWinLeave auto command can trigger a use-after-free if this auto command happens to reopen the same buffer in a new split window. This issue can potentially cause Vim to crash, leading to a denial of service.
Отчет
The impact is Low since the user must intentionally configure an uncommon auto command and run some buffer unload commands in order to trigger the issue.
