master-filter in printfilters-ppd 2.13 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/filter.debug temporary file. NOTE: the vendor disputes this vulnerability, stating 'this package does not have " possibility of attack with the help of symlinks"'
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
