Comment 7 Francisco Alonso 2014-08-11 14:43:50 UTC 
Statement:

This issue is not planned to be fixed in Red Hat Enterprise Linux 5 as it is now in Production 3 Phase of the support and maintenance life cycle, https://access.redhat.com/support/policy/updates/errata/
Comment 8 Martin Prpič 2014-10-07 08:44:49 UTC 
IssueDescription:

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.
