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.
For the stable distribution (squeeze), this problem has been fixed in
version 0.1.0-3.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 0.2.3-1.
We recommend that you upgrade your cups-pk-helper packages.
