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.

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.

hpssd in Hewlett-Packard Linux Imaging and Printing Project (hplip) 1.x and 2.x before 2.7.10 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a from address, which is not properly handled when invoking sendmail.
