Ubuntu Security Notice USN-2379-1
October 09, 2014

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:

Steven Vittitoe reported multiple stack buffer overflows in Linux kernel’s
magicmouse HID driver. A physically proximate attacker could exploit this
flaw to cause a denial of service (system crash) or possibly execute
arbitrary code via specially crafted devices. (CVE-2014-3181)

Ben Hawkes reported some off by one errors for report descriptors in the
Linux kernel’s HID stack. A physically proximate attacker could exploit
these flaws to cause a denial of service (out-of-bounds write) via a
specially crafted device. (CVE-2014-3184)

Several bounds check flaws allowing for buffer overflows were discovered in
the Linux kernel’s Whiteheat USB serial driver. A physically proximate
attacker could exploit these flaws to cause a denial of service (system
crash) via a specially crafted device. (CVE-2014-3185)

Steven Vittitoe reported a buffer overflow in the Linux kernel’s PicoLCD
HID device driver. A physically proximate attacker could exploit this flaw
to cause a denial of service (system crash) or possibly execute arbitrary
code via a specially craft device. (CVE-2014-3186)

A flaw was discovered in the Linux kernel’s associative-array garbage
collection implementation. A local user could exploit this flaw to cause a
denial of service (system crash) or possibly have other unspecified impact
by using keyctl operations. (CVE-2014-3631)

A flaw was discovered in the Linux kernel’s UDF filesystem (used on some
CD-ROMs and DVDs) when processing indirect ICBs. An attacker who can cause
CD, DVD or image file with a specially crafted inode to be mounted can
cause a denial of service (infinite loop or stack consumption).
(CVE-2014-6410)

James Eckersall discovered a buffer overflow in the Ceph filesystem in the
Linux kernel. A remote attacker could exploit this flaw to cause a denial
of service (memory consumption and panic) or possibly have other
unspecified impact via a long unencrypted auth ticket. (CVE-2014-6416)

James Eckersall discovered a flaw in the handling of memory allocation
failures in the Ceph filesystem. A remote attacker could exploit this flaw
to cause a denial of service (system crash) or possibly have unspecified
other impact. (CVE-2014-6417)

James Eckersall discovered a flaw in how the Ceph filesystem validates auth
replies. A remote attacker could exploit this flaw to cause a denial of
service (system crash) or possibly have other unspecified impact.
(CVE-2014-6418)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-37-generic 3.13.0-37.64
linux-image-3.13.0-37-generic-lpae 3.13.0-37.64
linux-image-3.13.0-37-lowlatency 3.13.0-37.64
linux-image-3.13.0-37-powerpc-e500 3.13.0-37.64
linux-image-3.13.0-37-powerpc-e500mc 3.13.0-37.64
linux-image-3.13.0-37-powerpc-smp 3.13.0-37.64
linux-image-3.13.0-37-powerpc64-emb 3.13.0-37.64
linux-image-3.13.0-37-powerpc64-smp 3.13.0-37.64

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.
