+Subject: [PATCH] ospfd: address CVE-2017-3224
+
+Based on the vulnerability mentioned in 793496 an attacker can craft an
+LSA with MaxSequence number wtih invalid links and not set age to MAX_AGE
+so the lsa would not be flush from the database.
+
+To address the issue, check incoming LSA is MaxSeq but Age is not set
+to MAX_AGE 3600, discard the LSA from processing it.
+Based on  RFC-2328 , When a LSA update sequence reaches MaxSequence
+number, it should be prematurely aged out from the database with age set
+to MAX_AGE (3600).
