cups: Incomplete fix for CVE-2014-3537
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.
It was discovered that CUPS allowed certain users to create symbolic links in certain directories under /var/cache/cups/. A local user with the 'lp' group privileges could use this flaw to read the contents of arbitrary files on the system or, potentially, escalate their privileges on the system.

CVE-2014-3537 CUPS vulnerability
Title: CUPS vulnerability
Summary: CUPS could be made to expose sensitive information, leading to privilege
escalation.
Francisco Alonso discovered that the CUPS web interface incorrectly
validated permissions on rss files. A local attacker could possibly use
this issue to bypass file permissions and read arbitrary files, possibly
leading to a privilege escalation.
Instructions: In general, a standard system update will make all the necessary changes.
