Glibc: Mega bug may hit thousands of devices

[avj]

I recommend that everyone run install updates to get the fixed package shown on the link provided by  shaggytwodope.

I have, and can confirm that the package

Code:

libc6                           2.19-0ubuntu6.7

was updated.

According to the link you need to restart your system for it to complete the process.

Code:

It was discovered that the GNU C Library incorrectly handled receiving
responses while performing DNS resolution. A remote attacker could use this
issue to cause the GNU C Library to crash, resulting in a denial of
service, or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 15.10:
  libc6                           2.21-0ubuntu4.1

Ubuntu 14.04 LTS:
  libc6                           2.19-0ubuntu6.7

Ubuntu 12.04 LTS:
  libc6                           2.15-0ubuntu10.13

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