========================================================================== Ubuntu Security Notice USN-4263-1 February 03, 2020
sudo vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Sudo could allow unintended access to the administrator account.
Software Description: - sudo: Provide limited super user privileges to specific users
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 19.10: sudo 1.8.27-1ubuntu4.1 sudo-ldap 1.8.27-1ubuntu4.1
Ubuntu 18.04 LTS: sudo 1.8.21p2-3ubuntu1.2 sudo-ldap 1.8.21p2-3ubuntu1.2
Ubuntu 16.04 LTS: sudo 1.8.16-0ubuntu1.9 sudo-ldap 1.8.16-0ubuntu1.9
In general, a standard system update will make all the necessary changes.
