Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue.(CVE-2023-48706)

Vim is an open source command line text editor. In affected versions when shifting lines in operator pending mode and using a very large value, it may be possible to overflow the size of integer. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `6bf131888` which has been included in version 9.0.2112. Users are advised to upgrade. There are no known workarounds for this vulnerability.(CVE-2023-48237)

Vim is an open source command line text editor. When using the z= command, the user may overflow the count with values larger than MAX_INT. Impact is low, user interaction is required and a crash may not even happen in all situations. This vulnerability has been addressed in commit `73b2d379` which has been included in release version 9.0.2111. Users are advised to upgrade. There are no known workarounds for this vulnerability.(CVE-2023-48236)

Vim is an open source command line text editor. When getting the count for a normal mode z command, it may overflow for large counts given. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `58f9befca1` which has been included in release version 9.0.2109. Users are advised to upgrade. There are no known ...
