Doc Type: If docs needed, set a value
Doc Text:
A heap use-after-free flaw was found in the vim package. When executing a `:s` command for the first time and using a sub-replace-special atom inside the substitution, it is possible that the recursive `:s` call causes memory to be freed, which may later then be accessed by the initial `:s` command. This issue may result in Vim crashing.

Description TEJ RATHI 2023-11-17 12:12:46 UTC 
Vim is an open source command line text editor. When closing a window, vim may try to access already freed window structure. Exploitation beyond crashing the application has not been shown to be viable. There are no known workarounds for this vulnerability.
