Ubuntu Security Notice USN-4263-2
February 05, 2020

sudo vulnerability
==========================================================================

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

- Ubuntu 14.04 ESM
- Ubuntu 12.04 ESM

Summary:

Sudo could allow unintended access to the administrator account.

Software Description:
- sudo: Provide limited super user privileges to specific users

Details:

USN-4263-1 fixed a vulnerability in Sudo. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

 Joe Vennix discovered that Sudo incorrectly handled memory operations when
 the pwfeedback option is enabled. A local attacker could possibly use this
 issue to obtain unintended access to the administrator account.

Update instructions:

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

Ubuntu 14.04 ESM:
  sudo                            1.8.9p5-1ubuntu1.5+esm3
  sudo-ldap                       1.8.9p5-1ubuntu1.5+esm3

Ubuntu 12.04 ESM:
  sudo                            1.8.3p1-1ubuntu3.9
  sudo-ldap                       1.8.3p1-1ubuntu3.9

In general, a standard system update will make all the necessary changes.
