The vold volume manager daemon on Android 3.0 and 2.x before 2.3.4
trusts messages that are received from a PF_NETLINK socket, which
allows local users to execute arbitrary code and gain root privileges
via a negative index that bypasses a maximum-only signed integer check
in the DirectVolume::handlePartitionAdded method, which triggers
memory corruption, as demonstrated by Gingerbreak.
