Description

OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. This package includes the core files necessary for both the OpenSSH client and server.

An authentication flaw was found in OpenSSH's privilege separation monitor. If it ever becomes possible to alter the behavior of the unprivileged process when OpenSSH is using privilege separation, an attacker may then be able to login without possessing proper credentials. (CVE-2006-5794)

Please note that this flaw by itself poses no direct threat to OpenSSH users. Without another security flaw that could allow an attacker to alter the behavior of OpenSSH's unprivileged process, this flaw cannot be exploited. There are currently no known flaws to exploit this behavior. However, we have decided to issue this erratum to fix this flaw to reduce the security impact if an unprivileged process flaw is ever found.

Users of openssh should upgrade to these updated packages, which contain a backported patch to resolve this issue.
