CVE-2015-8702
The DNS::GetResult function in dns.cpp in InspIRCd before 2.0.19 allows remote DNS servers to cause a denial of service (netsplit) via an invalid character in a PTR response, as demonstrated by a "\032" (whitespace) character in a hostname.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
