Summary:

Sun Solaris could allow a local attacker to launch a symlink attack, caused by a vulnerability in the libprint library. The fopen function in the nss_write.c file and the access function in lib/print/job.c file creates insecure temporary files. A local attacker could create a symbolic link for a file in /tmp to an arbitrary file on the system, which could allow the attacker to view, create or overwrite arbitrary files on the system.
