Description

In some cases, input events are sent to X servers not currently the VT owner, allowing a user to capture passwords. This update fixes this issue. CVE-2013-1940 has been assigned to this issue.

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