Vulnerability  : denial of service
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2011-1002
Debian Bug     : 614785

It was discovered that avahi, an implementation of the zeroconf protocol,
can be crashed remotely by a single UDP packet, which may result in a
denial of service.

For the oldstable distribution (lenny), this problem has been fixed in
version 0.6.23-3lenny3.

For the stable distribution (squeeze), this problem has been fixed in
version 0.6.27-2+squeeze1.

For the testing (wheezy) and unstable distribution (sid), this problem
has been fixed in version 0.6.28-4.

We recommend that you upgrade your avahi packages.
