Check for the version of the openssh packages Detailed Explanation for this Vulnerability Assessment Updated openssh packages that fix a potential security vulnerability and various other bugs are now available. This update has been rated as having low security impact by the Red Hat Security Response Team. OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. This includes the core files necessary for both the OpenSSH client and server. A bug was found in the way the OpenSSH server handled the MaxStartups and LoginGraceTime configuration variables. A malicious user could connect to the SSH daemon in such a way that it would prevent additional logins from occuring until the malicious connections are closed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-2069 to this issue. Additionally, the following issues are resolved with this update: - The -q option of the ssh client did not suppress the banner message sent by the server, which caused errors when used in scripts. - The sshd daemon failed to close the client connection if multiple X clients were forwarded over the connection and the client session exited. - The sftp client leaked memory if used for extended periods. - The sshd daemon called the PAM functions incorrectly if the user was unknown on the system. All users of openssh should upgrade to these updated packages, which contain backported patches and resolve these issues.
