Mandriva Linux Security Advisory 2015-108

Mandriva Linux Security Advisory 2015-108 - Cross-site scripting vulnerability in scheduler/client.c in Common Unix Printing System 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. 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. 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. A malformed file with an invalid page header and compressed raster data can trigger a buffer overflow in cupsRasterReadPixels.

Red Hat Security Advisory 2014-1388-02 - CUPS provides a portable printing layer for Linux, UNIX, and similar operating systems. A cross-site scripting flaw was found in the CUPS web interface. An attacker could use this flaw to perform a cross-site scripting attack against users of the CUPS web interface. 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.
