CVE-2008-1198: Red Hat Enterprise Linux

High severity, CVSS 7.1. EPSS: 2.4% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Enterprise Linux: version 4.0 only; version 3.0 only; version 5.0 only
