Description Jan Lieskovsky 2012-04-12 06:31:25 EDT
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).

Comment 1 Jan Lieskovsky 2012-04-12 06:38:57 EDT
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.

Comment 5 Jan Lieskovsky 2012-06-20 12:33:06 EDT

This issue did not affect the version of cobbler as shipped with Red Hat Network Satellite Server 5.4 as it did not include the upstream commit d7b30b5fca5097c544ca37ade8c945a3106b1896 that introduced this flaw.
