De-referencing null pointer for certain signature expire values.

Posting date: 
12 Nov 2002
Program Impacted: 
Versions affected:

Remote attackers can cause a denial of service (crash) via SIG RR elements with invalid expiry times, which are removed from the internal BIND database and later cause a null dereference.


Disable recursion, if possible.

None known at this time.

Upgrade to BIND 8.3.4 or later


ISC would like to thank Internet Security Systems for bringing this to our attention.
