This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
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.
