The set_mgmt_parameters function in item.py in cobbler before 2.2.2 allows context-dependent attackers to execute arbitrary code via vectors related to the use of the yaml.load function instead of the yaml.safe_load function, as demonstrated using Puppet.

This update for cobbler fixes the following issues :

  - Add cobbler-tests subpackage for unit testing for     openSUSE/SLE 

  - Adds LoadModule definitions for openSUSE/SLE

  - Switch to new refactored auth module.

  - Fix for kernel and initrd detection (boo#1159010)

  - New :

  - For the distro there is now a parameter     remote_boot_initrd and remote_boot_kernel ()

  - For the profile there is now a parameter filename for     DHCP. (#2280)

  - Signatures for ESXi 6 and 7 (#2308)

  - The hardlink command is now detected more dynamically     and thus more error resistant (#2297)

  - build server wants explicite package in BuildRequires;
    use tftp

  - require tftp(server) instead of atftp

  - rotate cobbler logs at higher frequency to prevent disk     fillup (boo#1113747)

  - Forbid exposure of private methods in the API     (CVE-2018-10931) (CVE-2018-1000225) (boo#1104287)     (boo#1104189) (boo#1105442)

  - Check access token when calling 'modify_setting' API     endpoint (boo#1104190) (boo#1105440) (CVE-2018-1000226)

Specially crafted YAML could allow attackers to execute arbitrary code due to the use of yaml.load instead of yaml.safe_load.
