Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow due to the improper handling of search patterns containing ASCII NUL characters in a specific configuration. An attacker can read beyond the buffer limits by manipulating the search pattern when certain settings (:set shm+=S and :set rl) are enabled.
Note:
This requires the search count functionality to be off and at the same time :set rightleft must have been used.
