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.
Weakness
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
