3. 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.

 

4. Solution:
