Original advisory details:

 Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory
 manager did not properly handle when applications grow stacks into adjacent
 memory regions. A local attacker could exploit this to gain control of
 certain applications, potentially leading to privilege escalation, as
 demonstrated in attacks against the X server. (CVE-2010-2240)

 Kees Cook discovered that under certain situations the ioctl subsystem for
 DRM did not properly sanitize its arguments. A local attacker could exploit
 this to read previously freed kernel memory, leading to a loss of privacy.
 (CVE-2010-2803)

 Ben Hawkes discovered an integer overflow in the Controller Area Network
 (CAN) subsystem when setting up frame content and filtering certain
 messages. An attacker could send specially crafted CAN traffic to crash the
 system or gain root privileges. (CVE-2010-2959)");
