Descriptions

CUPS before 2.0 allows local users to read arbitrary files via a symlink attack on (1) index.html, (2) index.class, (3) index.pl, (4) index.php, (5) index.pyc, or (6) index.py.

CUPS anterior a 2.0 permite a usuarios locales leer ficheros arbitrarios a través de un ataque de enlace simbólico sobre (1) index.html, (2) index.class, (3) index.pl, (4) index.php, (5) index.pyc o (6) index.py.

It was discovered that CUPS allowed certain users to create symbolic links in certain directories under /var/cache/cups/. A local user with the 'lp' group privileges could use this flaw to read the contents of arbitrary files on the system or, potentially, escalate their privileges on the system.
