HP Linux Imaging and Printing (HPLIP) before 3.13.2 uses world-writable permissions for /var/log/hp and /var/log/hp/tmp, which allows local users to delete log files via standard filesystem operations.

base/pkit.py in HP Linux Imaging and Printing (HPLIP) through 3.13.11 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/hp-pkservice.log temporary file.

upgrade.py in the hp-upgrade service in HP Linux Imaging and Printing (HPLIP) 3.x through 3.13.11 launches a program from an http URL, which allows man-in-the-middle attackers to execute arbitrary code by gaining control over the client-server data stream.

The check_permission_v1 function in base/pkit.py in HP Linux Imaging and Printing (HPLIP) through 3.13.9 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process.

HP Linux Imaging and Printing (HPLIP) through 3.12.4 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/hpcupsfilterc_#.bmp, (2) /tmp/hpcupsfilterk_#.bmp, (3) /tmp/hpcups_job#.out, (4) /tmp/hpijs_#####.out, or (5) /tmp/hpps_job#.out temporary file, a different vulnerability than CVE-2011-2722.

The send_data_to_stdout function in prnt/hpijs/hpcupsfax.cpp in HP Linux Imaging and Printing (HPLIP) 3.x before 3.11.10 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/hpcupsfax.out temporary file.

foomatic-rip-hplip in HP Linux Imaging and Printing (HPLIP) 3.11.5 allows remote attackers to execute arbitrary code via a crafted *FoomaticRIPCommandLine field in a .ppd file.

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.
