4Subject: [PATCH] [v9_9] limit recursion depth and iterative queries
5
64006. [security] A flaw in delegation handling could be exploited
7 to put named into an infinite loop. This has
8 been addressed by placing limits on the number
9 of levels of recursion named will allow (default 7),
10 and the number of iterative queries that it will
11 send (default 50) before terminating a recursive
12 query (CVE-2014-8500).
13
14 The recursion depth limit is configured via the
15 "max-recursion-depth" option. [RT #35780]
