Debian DLA-384-1 : inspircd security and regression update

high Nessus Plugin ID 87897

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected inspircd, and inspircd-dbg packages.
