DLA 1412-1: cups security update

Package : cups
Version : 1.7.5-11+deb8u3
CVE ID : CVE-2017-18190 CVE-2017-18248

Two vulnerabilities affecting the cups printing server were found
which can lead to arbitrary IPP command execution and denial of
service.

CVE-2017-18190

A localhost.localdomain whitelist entry in valid_host() in
scheduler/client.c in CUPS before 2.2.2 allows remote attackers to
execute arbitrary IPP commands by sending POST requests to the
CUPS daemon in conjunction with DNS rebinding. The
localhost.localdomain name is often resolved via a DNS server
(neither the OS nor the web browser is responsible for ensuring
that localhost.localdomain is 127.0.0.1).

CVE-2017-18248

The add_job function in scheduler/ipp.c in CUPS before 2.2.6, when
D-Bus support is enabled, can be crashed by remote attackers by
sending print jobs with an invalid username, related to a D-Bus
notification.

For Debian 8 "Jessie", these problems have been fixed in version
1.7.5-11+deb8u3.

We recommend that you upgrade your cups packages.
