Ubuntu Security Notice USN-2887-1
February 02, 2016
linux vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description:
– linux: Linux kernel
Details:
It was discovered that a use-after-free vulnerability existed in the
AF_UNIX implementation in the Linux kernel. A local attacker could use
crafted epoll_ctl calls to cause a denial of service (system crash) or
expose sensitive information. (CVE-2013-7446)
It was discovered that the KVM implementation in the Linux kernel did not
properly restore the values of the Programmable Interrupt Timer (PIT). A
user-assisted attacker in a KVM guest could cause a denial of service in
the host (system crash). (CVE-2015-7513)
Sasha Levin discovered that the Reliable Datagram Sockets (RDS)
implementation in the Linux kernel had a race condition when checking
whether a socket was bound or not. A local attacker could use this to cause
a denial of service (system crash). (CVE-2015-7990)
It was discovered that the Btrfs implementation in the Linux kernel
incorrectly handled compressed inline extants on truncation. A local
attacker could use this to expose sensitive information. (CVE-2015-8374)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS:
linux-image-3.13.0-77-generic 3.13.0-77.121
linux-image-3.13.0-77-generic-lpae 3.13.0-77.121
linux-image-3.13.0-77-lowlatency 3.13.0-77.121
linux-image-3.13.0-77-powerpc-e500 3.13.0-77.121
linux-image-3.13.0-77-powerpc-e500mc 3.13.0-77.121
linux-image-3.13.0-77-powerpc-smp 3.13.0-77.121
linux-image-3.13.0-77-powerpc64-emb 3.13.0-77.121
linux-image-3.13.0-77-powerpc64-smp 3.13.0-77.121
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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.

Several security issues were fixed in the kernel.
Software Description:
– linux-lts-trusty: Linux hardware enablement kernel from Trusty
Details:
It was discovered that a use-after-free vulnerability existed in the
AF_UNIX implementation in the Linux kernel. A local attacker could use
crafted epoll_ctl calls to cause a denial of service (system crash) or
expose sensitive information. (CVE-2013-7446)
