Title:	RedHat Security Advisory RHSA-2008:0855
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2008:0855. OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. Last week Red Hat detected an intrusion on certain of its computer systems and took immediate action. While the investigation into the intrusion is on-going, our initial focus was to review and test the distribution channel we use with our customers, Red Hat Network (RHN) and its associated security measures. Based on these efforts, we remain highly confident that our systems and processes prevented the intrusion from compromising RHN or the content distributed via RHN and accordingly believe that customers who keep their systems updated using Red Hat Network are not at risk. We are issuing this alert primarily for those who may obtain Red Hat binary packages via channels other than those of official Red Hat subscribers. In connection with the incident, the intruder was able to sign a small number of OpenSSH packages relating only to Red Hat Enterprise Linux 4 (i386 and x86_64 architectures only) and Red Hat Enterprise Linux 5 (x86_64 architecture only). As a precautionary measure, we are releasing an updated version of these packages, and have published a list of the tampered packages and how to detect them at http://www.redhat.com/security/data/openssh-blacklist.html To reiterate, our processes and efforts to date indicate that packages obtained by Red Hat Enterprise Linux subscribers via Red Hat Network are not at risk. These packages also fix a low severity flaw in the way ssh handles X11 cookies when creating X11 forwarding connections. When ssh was unable to create untrusted cookie, ssh used a trusted cookie instead, possibly allowing the administrative user of a untrusted remote server, or untrusted application run on the remote server, to gain unintended access to a users local X server. (CVE-2007-4752) Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2008-0855.html http://www.redhat.com/security/data/openssh-blacklist.html http://www.redhat.com/security/updates/classification/#critical Risk factor : High CVSS Score: 7.5
