>Severity:	serious
>Priority:	high

>Class:		sw-bug
>Release:	FreeBSD 7.1-PRERELEASE i386
>Environment:

System: FreeBSD 7.1-PRERELEASE i386

>Description:

Multiple vulnerabilities were discovered in the hplip 1.6.7 [1].  I had
analyzed RedHat patches [2] and [3]: first two (CVE-2008-2940) apply
"as-is" to FreeBSD's port (2.8.2_2) and the second one (CVE-2008-2941)
contains many fixes to the code that exists in 2.8.2_2 too.  So, I am
counting current FreeBSD port as vulnerable to both attacks.  Moreover,
I had traced the vulnerabilities through the release sources: proper
device_uri handling was introduced in 2.8.4 and parser fragility in
hpssd.py was eliminated in the same version, because hpssd was converted
to a systray application.  So, 2.8.4 and higher should not be vulnerable
to the described attacks.

>How-To-Repeat:

Look at the above references.

>Fix:

The following VuXML entry should be evaluated and added:

	<p>HP Linux Imaging and Printing System (HPLIP) is prone
	to multiple vulnerabilities, including privilege-escalation
	and denial-of-service issues.</p>
	<p>Exploiting the privilege-escalation vulnerability may
	allow attackers to perform certain actions with elevated
	privileges. Successful exploits of the denial-of-service
	issue will cause the 'hpssd' process to crash, denying
	service to legitimate users.</p>
	<p>These issues affect HPLIP 1.6.7; other versions may also
	be affected.</p>
