Description

PC Netlink for Solaris SPARC 7, 8 and 9 contains a flaw that may allow a malicious local user to manipulate arbitrary files on the system. The issue is due to the '/opt/lanman/sbin/slsmgr' script creating temporary files insecurely. It is possible for a user to use a symlink style attack to manipulate arbitrary files, resulting in a loss of integrity.
