upgrade.py in the hp-upgrade service in HP Linux Imaging and Printing (HPLIP) 3.x through 3.13.11 launches a program from an http URL, which allows man-in-the-middle attackers to execute arbitrary code by gaining control over the client-server data stream.

- fix-CVE-2013-6402.dif fixes hardcoded file name     /tmp/hp-pkservice.log in pkit.py (bnc#852368).

  - disable_hp-upgrade.patch disables hp-upgrade/upgrade.py     for security reasons (bnc#853405). To upgrade HPLIP an     openSUSE software package manager like YaST or zypper     should be used. (CVE-2013-6427)

Updated hplip packages fix security vulnerabilities :

It was discovered that the HPLIP Polkit daemon incorrectly handled temporary files. A local attacker could possibly use this issue to overwrite arbitrary files (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).

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities have been found in the HP Linux Printing and Imaging System: Insecure temporary files, insufficient permission checks in PackageKit and the insecure hp-upgrade service has been disabled.

New hplip packages are available for Slackware 14.0 to fix a security issue.
