RHSA-2010:0892 - Moderate: openswan security update

Synopsis

Moderate: openswan security update

Type/Severity

Security Advisory Moderate

Topic

Updated openswan packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

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.

Two buffer overflow flaws were found in the Openswan client-side XAUTH handling code used when connecting to certain Cisco gateways. A malicious or compromised VPN gateway could use these flaws to execute arbitrary code on the connecting Openswan client. (CVE-2010-3302, CVE-2010-3308)

Two input sanitization flaws were found in the Openswan client-side handling of Cisco gateway banners. A malicious or compromised VPN gateway could use these flaws to execute arbitrary code on the connecting Openswan client. (CVE-2010-3752, CVE-2010-3753)

Red Hat would like to thank the Openswan project for reporting these issues. Upstream acknowledges D. Hugh Redelmeier and Paul Wouters as the original reporters.

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.
