Description Ratul Gupta 2013-11-27 06:12:51 EST

A temporary file handling flaw was found in hplip/pkit.py. Because a predicatable temporary filename is used, an attacker could use a symlink attack to overwrite an arbitrary file with the privileges of the process running hplip.

This is a different flaw than CVE-2013-0200.

Comment 4 Huzaifa S. Sidhpurwala 2013-11-28 00:38:33 EST

Quoting from https://bugzilla.redhat.com/show_bug.cgi?id=1035244#c2

The affected code, which implements the BackendServer class, is shipped (base/pkit.py). However, it only does so if the "policy-kit" configuration variable is set to yes -- and that is not the default for Red Hat Enterprise Linux

Additionally, even if the configuration is changed, the BackendServer class is only instantiated in the pkservice.py module -- and this is explicitly *not* shipped

Statement:

Not Vulnerable. This issue does not affect the version of hplip as shipped with Red Hat Enterprise Linux 5 and 6. This issue does not affect the version of hplip3 as shipped with Red Hat Enterprise Linux 5.
