A security issue has been reported in Conky, which can be exploited by malicious, local users to perform certain actions with escalated privileges.
The security issue is caused due to Conky's "eve" module using the "/tmp/.cesf" file in an insecure manner, which can be exploited to e.g. overwrite arbitrary files with the privileges of the user running Conky.
Successful exploitation requires that the "eve" module is compiled and configured.
The security issue is reported in version 1.8.1. Other versions may also be affected.
Solution: Fixed in the GIT repository.
Provided and/or discovered by: Reported in an Ubuntu bug by segooon.
