Stack-based buffer overflow in the hpmud_get_pml function in io/hpmud/pml.c in Hewlett-Packard Linux Imaging and Printing (HPLIP) 1.6.7, 3.9.8, 3.10.9, and probably other versions allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SNMP response with a large length value.

The hpssd message parser in hpssd.py in HP Linux Imaging and Printing (HPLIP) 1.6.7 allows local users to cause a denial of service (process stop) via a crafted packet, as demonstrated by sending "msg=0" to TCP port 2207.

The alert-mailing implementation in HP Linux Imaging and Printing (HPLIP) 1.6.7 allows local users to gain privileges and send e-mail messages from the root account via vectors related to the setalerts message, and lack of validation of the device URI associated with an event message.
