What is CVE-2016-10396?
CVE-2016-10396 is a high-severity denial of service vulnerability in n/a, published on 6 Jul 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The racoon daemon in IPsec-Tools 0.8.2 contains a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.
Weakness: CWE-407
