CVE-2016-2054
Multiple buffer overflows in xymond/xymond.c in xymond in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a long filename, involving handling a "config" command.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
