Description

The OpenSSH release 4.5 contains a security fix which has been backported to the openssh versions in our old products.

CVE-2006-5794: Incorrect return argument checking in the privilege separation monitor was fixed. In case of an exploitable unprivileged helper this could have been used to elevate privileges.
