The web interface in CUPS 1.7.4 allows local users in the lp group to read arbitrary files via a symlink attack on a file in /var/cache/cups/rss/ and language[0] set to null. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3537.
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.
