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.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
