linux-ec2 vulnerabilities

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

- Ubuntu 10.04 LTS


Several security issues were fixed in the kernel.

Software Description:
- linux-ec2: Linux kernel for EC2


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)

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).

Update instructions:

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-371-ec2      2.6.32-371.87

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.

  CVE-2014-3184, CVE-2014-3185, CVE-2014-6410
