Red Hat: 2010:0892-01: openswan: Moderate Advisory
Summary
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.
