EG Secure Solutions SiteGuard Server Edition contains an OS command injection vulnerability which may allow an attacker to execute arbitrary OS commands with root or SYSTEM privileges on the system running the affected product.

A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
