CVE-2018-1634
IBM Informix Dynamic Server Enterprise Edition 12.1 could allow a local user logged in with database administrator user to gain root privileges through a symbolic link vulnerability in infos.DBSERVERNAME.
Does this matter?
Lower severity and a low EPSS score (0.42%). Track it; it rarely justifies an emergency change on its own.
