CVE-2023-48231

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.
