Description

It is found that lxdm does not close file descriptor for log file althouhg it should. Also session started via lxdm can allow any local user to connect X. This new rpm should fix these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
