Details

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.

Ubuntu 14.04

Ubuntu 12.04

• cups - 1.5.3-0ubuntu8.4
