Test ID:1.3.6.1.4.1.25623.1.0.63043
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-696-1 (avahi)
Summary:Ubuntu USN-696-1 (avahi)

announced via advisory USN-696-1.

A security issue affects the following Ubuntu releases:

affected Ubuntu 6.06 LTS. (CVE-2007-3372)

Hugo Dias discovered that Avahi did not properly verify it's input when
processing mDNS packets. A remote attacker could send a crafted mDNS packet
