MiracleLinux 4 : openswan-2.6.32-4.2.0.1.AXS4 (AXSA:2011-553:01)

high Nessus Plugin ID 284113

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 4 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2011-553:01 advisory.

Openswan is a free implementation of IPsec & IKE for Linux. IPsec is the Internet Protocol Security and uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted net is encrypted by the ipsec gateway machine and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network or VPN.
This package contains the daemons and userland tools for setting up Openswan. It supports the NETKEY/XFRM IPsec kernel stack that exists in the default Linux kernel.
Openswan 2.6.x also supports IKEv2 (RFC4306) CVE-2011-3380 Openswan 2.6.29 through 2.6.35 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto IKE daemon crash) via an ISAKMP message with an invalid KEY_LENGTH attribute, which is not properly handled by the error handling function.
Fixed bugs:
- Whether the hostname or the ipaddress parameter is configured, Openswan now correctly sets up policies with the correct protocol and port.
- Previously, very large security label strings coming from the peer were truncated, then used. This truncated string could sometimes correspond to a valid string, leading to incorrect policies. This has been fixed. It also fixes an incorrect handling of the IKE setup
- Openswan can now be correctly set up in AH mode SAs.
- IPsec connections over a loopback interface did not work properly when a specific port was configured.
This has been fixed.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected openswan package.
