hplip vulnerabilities
==========================
==========================
========================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in HPLIP.

Software Description:
- hplip: HP Linux Printing and Imaging System (HPLIP)

Details:

It was discovered that the HPLIP Polkit daemon incorrectly handled
temporary files. A local attacker could possibly use this issue to
overwrite arbitrary files. In the default installation of Ubuntu 12.04 LT=
S
and higher, this should be prevented by the Yama link restrictions.
(CVE-2013-6402)

It was discovered that HPLIP contained an upgrade tool that would downloa=
d
code in an unsafe fashion. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could be exploited to execute arbitra=
ry
code. (CVE-2013-6427)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
hplip 3.13.9-1ubuntu0.1

Ubuntu 12.10:
hplip 3.12.6-3ubuntu4.3

Ubuntu 12.04 LTS:
hplip 3.12.2-1ubuntu3.4

Ubuntu 10.04 LTS:
hplip 3.10.2-2ubuntu2.5

In general, a standard system update will make all the necessary changes.=
