Description Francisco Alonso 2014-08-11 14:07:41 UTC 
It was reported [1] that CUPS does not check that files have world-readable permissions, which allow to local users to obtain sensitive information.

Upstream patches are available at [2] as well.

Comment 1 Francisco Alonso 2014-08-11 14:42:27 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 4 Francisco Alonso 2014-08-11 14:46:02 UTC 
Created cups tracking bugs for this issue:

Affects: fedora-all [bug 1128795]
Comment 5 Tim Waugh 2014-08-11 16:08:42 UTC 
The original upstream fix was in STR #4455.

This caused a regression: 'cupsctl -U root' now fails, as does 'View Error Log' in the web interface.

The regression is STR #4461. I've made a patch for this:

Comment 7 Martin Prpič 2014-10-07 08:44:45 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.
