Hewlett-Packard Linux Imaging and Printing provides drivers for Hewlett-Packard printers and multifunction peripherals, and tools for installing, using, and configuring them. 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. Red Hat would like to thank Sebastian Krahmer of the SuSE Security Team for reporting this issue. Users of hplip should upgrade to these updated packages, which contain a backported patch to correct this issue.
