Package        : ipsec-tools
Version        : 1:0.8.0-14+deb7u1
CVE ID         : CVE-2016-10396
Debian Bug     : 867986

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.
