Detailsinfo

A vulnerability, which was classified as problematic, was found in Ipsec-tools 0.8.2. This affects an unknown function of the component racoon Daemon. The manipulation as part of a ISAKMP Fragment leads to a algorithmic complexity vulnerability. CWE is classifying the issue as CWE-407. An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached. This is going to have an impact on availability. The summary by CVE is:

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.

The bug was discovered 07/10/2017. The weakness was published 07/06/2017 (Website). It is possible to read the advisory at cvsweb.netbsd.org. This vulnerability is uniquely identified as CVE-2016-10396 since 07/05/2017. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1499 according to MITRE ATT&CK.

The vulnerability scanner Nessus provides a plugin with the ID 102042 (Debian DLA-1044-1 : ipsec-tools security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l.
