Description


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.

Restrict local access to trusted users only.
