FreeBSD : maradns -- denial of service when resolving a long DNS hostname (8015600f-2c80-11e0-9cc1-00163e5bf4f9)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

MaraDNS developer Sam Trenholme reports :

... a mistake in allocating an array of integers, allocating it in
bytes instead of sizeof(int) units. This resulted in a buffer being
too small, allowing it to be overwritten. The impact of this
programming error is that MaraDNS can be crashed by sending MaraDNS a
single 'packet of death'. Since the data placed in the overwritten
array can not be remotely controlled (it is a list of increasing
integers), there is no way to increase privileges exploiting this bug.
