"Adam <[email protected]>, upstream author of inspircd found the Debian
patch that fixed CVE-2012-1836 was incomplete. Furthermore, it
introduced an issue, since invalid dns packets caused an infinite
loop. This upload corrects these problems.

As of today, no CVEs has been assigned to these Debian-specific flaws.

For the Squeeze distribution, these issues have been fixed in version
1.1.22+dfsg-4+squeeze2 of inspircd.

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."
