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 LTS
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 download
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 arbitrary
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.
