CVE-2006-2076
Memory leak in Paul Rombouts pdnsd before 1.2.4 allows remote attackers to cause a denial of service (memory consumption) via a DNS query with an unsupported (1) QTYPE or (2) QCLASS, as demonstrated by the OUSPG PROTOS DNS test suite.
Does this matter?
Lower severity and a low EPSS score (4.85%). Track it; it rarely justifies an emergency change on its own.
