CVE-2019-4655
IBM MQ 9.1.0.0, 9.1.0.1, 9.1.0.2, 9.1.0.3, 9.1.1, 9.1.2, and 9.1.3 is vulnerable to a denial of service attack that would allow an authenticated user to reset client connections due to an error within the Data Conversion routine.
Does this matter?
Lower severity and a low EPSS score (1.26%). Track it; it rarely justifies an emergency change on its own.
