USN-1514-1 : linux-ti-omap4 vulnerabilities

Ubuntu Security Notice (C) 2012 Canonical, Inc. / NASL script (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

A flaw was discovered in the Linux kernel's macvtap device driver,
which is used in KVM (Kernel-based Virtual Machine) to create a
network bridge between host and guest. A privleged user in a guest
could exploit this flaw to crash the host, if the vhost_net module is
loaded with the experimental_zcopytx option enabled. (CVE-2012-2119)

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface
(which is not available to unprivileged users until granted by a root
user) could exploit this flaw to crash the system or potential gain
administrative privileges. (CVE-2012-2136)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual
Machine) subsystem handled MSI (Message Signaled Interrupts). A local
unprivileged user could exploit this flaw to cause a denial of
service or potentially elevate privileges. (CVE-2012-2137)

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-2012-2372)

Ulrich Obergfell discovered an error in the Linux kernel's memory
management subsystem on 32 bit PAE systems with more than 4GB of
memory installed. A local unprivileged user could exploit this flaw
to crash the system. (CVE-2012-2373)

Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field
Communication Controller Interface). A remote attacker could exploit
these flaws to crash the system or potentially execute privileged
code. (CVE-2012-3364)

A flaw was discovered in the Linux kernel's epoll system call. An
unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system,
which is used to mount some CD-ROMs and DVDs. An unprivileged local
user could use these flaws to crash the system. (CVE-2012-3400)
