========================================================================== Ubuntu Security Notice USN-3973-1 May 13, 2019
isc-dhcp vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS
Summary:
DHCP could be made to crash if it received specially crafted network traffic.
Software Description: - isc-dhcp: DHCP server and client
Details:
It was discovered that DHCP, when built with a mismatched external BIND library, incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause DHCP 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 18.10: isc-dhcp-server 4.3.5-3ubuntu9.1
Ubuntu 18.04 LTS: isc-dhcp-server 4.3.5-3ubuntu7.1
In general, a standard system update will make all the necessary changes.
