- Date Reported:
- 30 Jul 2017
- Affected Packages:
- ipsec-tools
- Vulnerable:
- Yes
- Security database references:
- In the Debian bugtracking system: Bug 867986.
In Mitre's CVE dictionary: CVE-2016-10396. - More information:
-
The racoon daemon in IPsec-Tools 0.8.2 and earlier 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.
For Debian 7
Wheezy
, these problems have been fixed in version 1:0.8.0-14+deb7u2.We recommend that you upgrade your ipsec-tools packages.
