avahi - denial of service

Two denial of service conditions were discovered in avahi, a Multicast
DNS implementation.

Huge Dias discovered that the avahi daemon aborts with an assert error
if it encounters a UDP packet with source port 0 (CVE-2008-5081).

It was discovered that the avahi daemon aborts with an assert error if
it receives an empty TXT record over D-Bus (CVE-2007-3372).

For the stable distribution (etch), these problems have been fixed in
version 0.6.16-3etch2.

For the unstable distribution (sid), these problems have been fixed in
version 0.6.23-3.

We recommend that you upgrade your avahi packages.
