Red Hat Security Advisory 2012-0312-03 - The initscripts package contains system scripts to boot your system, change runlevels, activate and deactivate most network interfaces, and shut the system down cleanly. With the default IPsec ifup script configuration, the racoon IKE key management daemon used aggressive IKE mode instead of main IKE mode. This resulted in the preshared key hash being sent unencrypted, which could make it easier for an attacker able to sniff network traffic to obtain the plain text PSK from a transmitted hash.
