It was discovered that the ISC DHCPv6 server does not correctly
process requests which come from unexpected source addresses, leading
to an assertion failure and a daemon crash.

The oldstable distribution (lenny) is not affected by this problem.

For the stable distribution (squeeze), this problem has been fixed in
version 4.1.1-P1-15+squeeze1.
