A vulnerability has been found and corrected in hplip:

A flaw was found in the way certain HPLIP tools discovered devices
using the SNMP protocol. If a user ran certain HPLIP tools that search
for supported devices using SNMP, and a malicious user is able to send
specially-crafted SNMP responses, it could cause those HPLIP tools
to crash or, possibly, execute arbitrary code with the privileges of
the user running them (CVE-2010-4267).
