Details

In ISC DHCP 4.4.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1, when the function optioncodehashlookup() is called from addoption(), it increases the option's refcount field. However, there is not a corresponding call to optiondereference() to decrement the refcount field. The function addoption() is only used in server responses to lease query packets. Each lease query response calls this function for several options, so eventually, the reference counters could overflow and cause the server to abort.
