Debian Security Advisory

DLA-1044-1 ipsec-tools -- LTS security update

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.
