Rocket Software UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 suffer from a buffer overflow in an API function, where a string is copied into a caller-provided buffer without checking the length. This requires a valid login to exploit.
