A flaw was discovered in Avahi’s handling of compressed DNS packets.
If a specially crafted reply were received over the network, the Avahi daemon would go into an infinite loop, causing a denial of service.

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