Description David Walser 2012-10-24 20:43:01 CEST

Debian has issued an advisory on October 23:
http://www.debian.org/security/2012/dsa-2562

Updated package uploaded for Cauldron; patched package uploaded for Mageia 2.

Advisory:
========================

Updated cups-pk-helper package fixes security vulnerability:

cups-pk-helper, a PolicyKit helper to configure CUPS with fine-grained
privileges, wraps CUPS function calls in an insecure way. This could lead to
uploading sensitive data to a CUPS resource, or overwriting specific files
with the content of a CUPS resource. The user would have to explicitly
approve the action (CVE-2012-4510).

No public poc that I've been able to find.

As /usr/lib64/cups-pk-helper-mechanism handles the dbus changes for
printers, for testing, just ensuring system-config-printer can
disable and enable a printer.

Testing shortly.

Testing complete on Mageia 2 i586 and x86-64.

Could someone from the sysadmin team push the srpm
cups-pk-helper-0.2.1-1.mga2.src.rpm
from Mageia 2 Core Updates Testing to Core Updates.
