21 January 2014

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
