install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION

* CVE-2012-2372: Denial of service in Reliable Datagram Sockets protocol.

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw
to cause a denial of service.


* CVE-2012-3400: Buffer overflow in UDF parsing.

A bug in the kernel's UDF file system driver could be exploited by an
unprivileged local user to crash the system.


* CVE-2012-0044: Integer overflow and memory corruption in DRM CRTC support.

A missing size check in drm_mode_dirtyfb_ioctl allowed an attacker to
overflow num_clips, causing a buffer allocation of an unintended,
small size. Future calls to fb->funcs->dirty could result in memory
corruption beyond that buffer.
