pysmb.py in system-config-printer 0.6.x and 0.7.x, as used in foomatic-gui and possibly other products, allows remote SMB servers to execute arbitrary commands via shell metacharacters in the (1) NetBIOS or (2) workgroup name, which are not properly handled when searching for network printers.

This update fixes a typo from the previous update :

system-config-printer used an unauthenticated connection when downloading printer drivers from openprinting.org (CVE-2011-4405).
This update disables the printer driver download feature.

system-config-printer did not properly quote shell meta characters in SMB server or workgroup names when passing them to the shell (CVE-2011-2899).

- Add system-config-printer-subprocess-no-shell.patch:
    avoid escaping issues when running commands. Fix     bnc#735322.

  - Add system-config-printer-no-openprinting.patch: this     disables the feature where PPD drivers can be downloaded     from OpenPrinting.org. See discussion in bnc#733542. As     a side-effect, this fixes CVE-2011-4405.
