A security issue has been reported in SLiM, which can be exploited by malicious, local users to disclose sensitive information.
The security issue is caused due to the application generating the X authority file by passing the X authority cookie via the command line to "xauth". This can be exploited to disclose the X authority cookie by consulting the process list and e.g. gain access the user's display.
The security issue is reported in version 1.3.0. Other versions may also be affected.
Solution: Restrict local access to trusted users only.
