Ubuntu 4.10 / 5.04 / 5.10 : ipsec-tools vulnerability (USN-221-1)

high Nessus Plugin ID 20763

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

The Oulu University Secure Programming Group discovered a remote Denial of Service vulnerability in the racoon daemon. When the daemon is configured to use aggressive mode, then it did not check whether the peer sent all required payloads during the IKE negotiation phase.
A malicious IPsec peer could exploit this to crash the racoon daemon.

Please be aware that racoon is not officially supported by Ubuntu, the package is in the 'universe' component of the archive.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ipsec-tools and / or racoon packages.
