Forbes compiled a list of the seven Most-Hacked software titles for 2009.  They took a survey of security professionals from various companies including Verisign, TippingPoint, iDefense and Qualys.  Based on this survey, Forbes found that the following were the most hacked software titles from 2009.

Gnome Screensaver authentication bypass vulnerability (Ubuntu, maybe others)

http://www.securityfocus.com/bid/37240/info

This reminds me of the days of Windows 95/3.1 where you could bypass the
screensaver just by hitting the right sequence of keys.

This vulnerability specifically targets Ubuntu, but may be applicable to
other installations of v2.28 as well.

Testing the exploit under Fedora 11 and 12 does not duplicate the issue.

It is recommended for Ubuntu users to update their machines to the
latest version of gnome-screensaver to avoid this issue.

RHSA-2009:1659-1: Moderate: kvm security and bug fix update, guest could cause DoS of host machine

http://rhn.redhat.com/errata/RHSA-2009-1659.html

A moderate security vulnerability could allow a malicious user on a
guest VM to cause a DoS attack on the underlying host.

This patch also updates a few other non-security related bugs in the
software as explained at the above link.

It is recommended to update to a version of KVM that includes these
security fixes.
