Stefan Nordhausen has discovered a vulnerability in net-acct, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.
The "write_list()" and "dump_curr_list()" functions create temporary files insecurely. This can be exploited via symlink attacks to overwrite or create arbitrary files with the privileges of a user executing net-acct.
