Ubuntu Security Notice USN-2796-1
November 05, 2015

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

Dmitry Vyukov discovered that the Linux kernel did not properly initialize
IPC object state in certain situations. A local attacker could use this to
escalate their privileges, expose confidential information, or cause a
denial of service (system crash). (CVE-2015-7613)

It was discovered that the Linux kernel did not check if a new IPv6 MTU set
by a user space application was valid. A remote attacker could forge a
route advertisement with an invalid MTU that a user space daemon like
NetworkManager would honor and apply to the kernel, causing a denial of
service. (CVE-2015-0272)

It was discovered that in certain situations, a directory could be renamed
outside of a bind mounted location. An attacker could use this to escape
bind mount containment and gain access to sensitive information.
(CVE-2015-2925)

Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained
hardcoded attributes about the USB devices. An attacker could construct a
fake WhiteHEAT USB device that, when inserted, causes a denial of service
(system crash). (CVE-2015-5257)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.2.0-1473-omap4 3.2.0-1473.95

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
