CFITSIO before version 3.43 unsafely uses sprintf() in multiple files without checking input size. A remote unauthenticated attacker could exploit this to execute arbitrary code.

The CVE-2018-1000166 is possibly a duplicate of CVE-2018-3846, CVE-2018-3848 and CVE-2018-3849.

Looks like you are correct. Changed CVE-2018-1000166 to CVE-2018-3846 and filed separate BZ for CVE-2018-3848 and CVE-2018-3849.
