Yes it is. Is it opensuse only?
No. It also affects all versions. Also, just to clarify, lightdm-gtk-greeter is a separate project and not related to lightdm, upstream is at https://launchpad.net/lightdm-gtk-greeter. I have a maintenance update in home:gberh:branches:OBS_Maintained:lightdm-gtk-greeter. Should I request a CVE? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
