Secunia

Gentoo has issued an update for ed. This fixes an old vulnerability, which can be exploited by malicious, local users to perform certain actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to temporary files being created insecurely. This can be exploited via symlink attacks to overwrite or create arbitrary files with the privileges of the user running ed.

Solution
Update to "sys-apps/ed-0.2-r4" or later.
