Ubuntu 20.04 UBUNTU-2023-0475 Critical: DNS Resolver Patch Available

fedora
Calendar Grey September 13, 2005
Dist Fedora Esm H88
Ubuntu 20.04 update addresses significant DNS resolver vulnerabilities, improving network settings with upgraded functionalities.
Updated package.

Summary

DHCP (Dynamic Host Configuration Protocol) is a protocol which allows

individual devices on an IP network to get their own network

configuration information (IP address, subnetmask, broadcast address,

etc.) from a DHCP server. The overall purpose of DHCP is to make it

easier to administer a large network. The dhcp package includes the

DHCP server and a DHCP relay agent.

You should install dhcp if you want to set up a DHCP server on your

network. You will also need to install the pump package, which

provides the DHCP client daemon, on client machines.

- fix bug 167273: time-offset should not set timezone by default

tzdata's Etc/* files are named with reverse sign

for hours west - ie. 'GMT+5' is GMT offset -18000seconds.

* Mon Aug 29 2005 Jason Vas Dias - 10:3.0.2-18

- fix bug 166926: make dhclient-script handle interface-mtu option

make dhclient-script support /etc/dhclient{,-$IF}-{up,down}-hooks scripts

to allow easy customization to support other non-default DHCP options - documented in 'man 8 dhclient-script' .

- handle the 'time-offset' DHCP option, requested by default.

* Tue Aug 23 2005 Jason Vas Dias 10:3.0.2-16

- fix bug 160655: strip trailing ' bytes from text options before append

- fix bug 163203: silence ISC blurb on configtest

- improve dhclient-script restarting of ypbind on yp.conf changes

- remove the 1-5 second wait on dhclient startup altogether

- change ISC version string to 'V3.0.2-RedHat' at request of ISC

- Allow package to compile with glibc-headers-2.3.5-10.3 (tr.c's use of __u16)

- don't explicitly require 2.2 era kernel, it's fairly overkill at this point
