CVE-2014-3683
Integer overflow in rsyslog before 7.6.7 and 8.x before 8.4.2 and sysklogd 1.5 and earlier allows remote attackers to cause a denial of service (crash) via a large priority (PRI) value.
Does this matter?
Lower severity and a low EPSS score (4.58%). Track it; it rarely justifies an emergency change on its own.
