Updated cups packages fix security vulnerabilities:

Cross-site scripting (XSS) vulnerability in scheduler/client.c
in Common Unix Printing System (CUPS) before 1.7.2 allows remote
attackers to inject arbitrary web script or HTML via the URL path,
related to the is_path_absolute function (CVE-2014-2856).

In CUPS before 1.7.4, a local user with privileges of group=lp
can write symbolic links in the rss directory and use that to gain
‘@SYSTEM’ group privilege with cupsd (CVE-2014-3537).

It was discovered that the web interface in CUPS incorrectly
validated permissions on rss files and directory index files. A local
attacker could possibly use this issue to bypass file permissions
and read arbitrary files, possibly leading to a privilege escalation
(CVE-2014-5029, CVE-2014-5030, CVE-2014-5031).

A malformed file with an invalid page header and compressed raster data
can trigger a buffer overflow in cupsRasterReadPixels (CVE-2014-9679).
