Description:
Eric Romang has reported a vulnerability in ekg, 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 in "/tmp" insecurely by "contrib/scripts/linki.py". This can be exploited via symlink attacks to create or overwrite arbitrary files, and potentially execute arbitrary commands with the privileges of the user running the affected script.
The vulnerability has been reported in all versions released prior to 5 June 2005, 22:03. Other versions may also be affected.
Solution:
The vulnerability has been fixed in version 1.6rc2.
