Ubuntu Security Notice (C) 2010-2014 Canonical, Inc. / NASL script (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.3
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
