10 August 2020
Samba could be made to crash if it received specially crafted network traffic.
- samba - SMB/CIFS file, print, and login server for Unix
USN-4454-1 fixed a vulnerability in Samba. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.
Original advisory 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.
