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 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.
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.
