RHEL 5 : openswan (RHSA-2009:0402)

high Nessus Plugin ID 36065

Synopsis

The remote Red Hat host is missing one or more security updates for openswan.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:0402 advisory.

Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec 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 network 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 (VPN).

Gerd v. Egidy discovered a flaw in the Dead Peer Detection (DPD) in Openswan's pluto IKE daemon. A remote attacker could use a malicious DPD packet to crash the pluto daemon. (CVE-2009-0790)

It was discovered that Openswan's livetest script created temporary files in an insecure manner. A local attacker could use this flaw to overwrite arbitrary files owned by the user running the script. (CVE-2008-4190)

Note: The livetest script is an incomplete feature and was not automatically executed by any other script distributed with Openswan, or intended to be used at all, as was documented in its man page. In these updated packages, the script only prints an informative message and exits immediately when run.

All users of openswan are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the ipsec service will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL openswan package based on the guidance in RHSA-2009:0402.
