Several security issues were fixed in HPLIP.

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)
