USN-2085-1: HPLIP vulnerabilities

Releases

• Ubuntu 13.10
• Ubuntu 12.10
• Ubuntu 12.04
• Ubuntu 10.04

Packages

• 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
machine-in-the-middle attack, this flaw could be exploited to execute arbitrary
code. (CVE-2013-6427)

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

• hplip - 3.12.2-1ubuntu3.4

Ubuntu 10.04
