Description David Walser 2013-04-18 21:29:02 CEST

Debian and Ubuntu have issued advisories on April 17:
http://www.debian.org/security/2013/dsa-2661
http://www.ubuntu.com/usn/usn-1803-1/

Thomas Backlund fixed it in Cauldron yesterday with x11-server-1.13.4-1.mga3.

Patched package uploaded for Mageia 2.

Patched added in Mageia 1 SVN.

Advisory:
========================

Updated x11-server packages fix security vulnerability:

It was discovered that the X.Org X server did not properly clear input
events in certain circumstances. A local attacker with physical access
could use this flaw to capture keystrokes (CVE-2013-1940).

Comment 2 Bill Wilkinson 2013-04-30 17:33:06 CEST

Testing MGA2-32.  Unable to reproduce bug under switch conditions with KDE. The PoC used gnome, which won't allow user switching without GDM as display manager.

Tested general use, all OK.  Tried switching again, still no pw in the text editor of first account.
