CVE-2024-41965 Information

Description

Vim is an open source command line text editor. double-free in dialog_changed() in Vim < v9.1.0648. When abandoning a buffer Vim may ask the user what to do with the modified buffer. If the user wants the changed buffer to be saved Vim may create a new Untitled file if the buffer did not have a name yet. However when setting the buffer name to Unnamed Vim will falsely free a pointer twice leading to a double-free and possibly later to a heap-use-after-free which can lead to a crash. The issue has been fixed as of Vim patch v9.1.0648.
