"It was discovered that InspIRCd did not validate the names in DNS
responses before using them in inter-server communication. A remote
attacker controlling the reverse DNS server for an IRC client could
use this for denial of service or possibly for privilege escalation on
the IRC network.

InspIRCd appears to have been completely unusable since version
1.1.22+dfsg-4+squeeze1 due to a bug in its build system triggered by
(e)glibc versions newer than 2.9. This has also been fixed.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
