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.
