========================================================================== Ubuntu Security Notice USN-4454-1 August 10, 2020
samba vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Samba could be made to crash if it received specially crafted network traffic.
Software Description: - samba: SMB/CIFS file, print, and login server for Unix
Details:
Martin von Wittich and Wilko Meyer discovered that Samba incorrectly handled certain empty UDP packets when being used as a AD DC NBT server. A remote attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: samba 2:4.11.6+dfsg-0ubuntu1.4
Ubuntu 18.04 LTS: samba 2:4.7.6+dfsg~ubuntu-0ubuntu2.18
Ubuntu 16.04 LTS: samba 2:4.3.11+dfsg-0ubuntu0.16.04.29
In general, a standard system update will make all the necessary changes.
