CVE-2014-2746
net/IOService.java in Tigase before 5.2.1 does not properly restrict the processing of compressed XML elements, which allows remote attackers to cause a denial of service (resource consumption) via a crafted XMPP stream, aka an "xmppbomb" attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
