CVE-2008-1198 Information

Description

The default IPSec ifup script in Red Hat Enterprise Linux 3 through 5 configures racoon to use aggressive IKE mode instead of main IKE mode which makes it easier for remote attackers to conduct brute force attacks by sniffing an unencrypted preshared key (PSK) hash.
