ipsec-tools vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10

Software Description

Details

Sebastian Krahmer discovered a Denial of Service vulnerability in the racoon daemon. By sending specially crafted ISAKMP packets, a remote attacker could trigger a buffer overflow which caused racoon to crash.

This update does not introduce any source code changes affecting the ipsec-tools package. It is necessary to update the version number of the package in order to support an update to the “racoon” package. Please note that racoon is not officially supported by Ubuntu (it is in the “universe” component of the archive).

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 4.10
racoon
