A privilege escalation flaw was found in the way Cobbler, a network install server, processed certain YAML strings passed through the Puppet management parameters interface. A remote attacker could provide a specially-crafted management parameter YAML string, which once loaded by Cobbler could lead to arbitrary code execution with the privileges of the privileged system user (root).

This issue affects the versions of the cobbler package, as shipped with Fedora EPEL 5 and Fedora EPEL 6. Please schedule an update. As of right now, this issue did NOT affect the current versions of the cobbler package, as shipped with Fedora release of 15 and 16 (the cobbler-2.0.11-3.* versions). But since there are cobbler-2.2.2-1.fc* versions scheduled to get next stable versions and these are affected too, please schedule Fedora release 15 and 16 cobbler package versions updates too.
