(RHSA-2011:0300) Moderate: Red Hat Network Satellite Server security update

Red Hat Network Satellite Server (RHN Satellite Server) is a system
management tool for Linux-based infrastructures. It allows for the
provisioning, remote management and monitoring of multiple Linux
deployments with a single, centralized tool.

A session fixation flaw was found in the way RHN Satellite Server handled
session cookies. An RHN Satellite Server user able to pre-set the session
cookie in a victim’s browser to a valid value could use this flaw to hijack
the victim’s session after the next log in. (CVE-2011-0717)

A flaw was found in the way RHN Satellite Server managed user
authentication. A time delay was not inserted after each failed log in,
which could allow a remote attacker to conduct a password guessing attack
efficiently. (CVE-2011-0718)

Red Hat would like to thank Thomas Biege of the SuSE Security Team for
reporting these issues.

Users of RHN Satellite Server 5.4 are advised to upgrade to these updated
packages, which contain backported patches to correct these issues. RHN
Satellite Server must be restarted (“rhn-satellite restart”) for this
update to take effect.
