* SECURITY UPDATE: Properly handle multiple netmasks in sudoers Host and
  Host_List values
  - match.c: Prevent IPv6 netmask-based address matching logic from
    incorrectly being applied to IPv4 addresses. Based on upstream patch
    written by Todd C. Miller.
  - CVE-2012-2337

39. By Jamie Strandboge on 2011-01-19

* SECURITY UPDATE: privilege escalation via -g when using group Runas_List
  - pwutil.c, sudo.h: add user_in_group(), backported from upstream commits
    48ca8c2eddf8, 72df368a8a0e and 6ebc55d4716b. This is intended to be used
    only with check.c to fix CVE-2011-0010 instead of doing the refactoring.
    Going forward, will need to look at this code also if a flaw is found in
    this refactored code. If needed, the refactoring work is in 48ca8c2eddf8
    and 6ebc55d4716b.
  - check.c: prompt for password when the user is running sudo as himself
    but as a different group. Backported from fe8a94f96542.
  - CVE-2011-0010

* SECURITY UPDATE: privilege escalation via '-g' option when using
  'user:group' in Runas_Spec
  - update match.c to verify both user and group match sudoers when using
    '-g'. Patch thanks to upstream.
  - CVE-2010-2956

* SECURITY UPDATE: properly handle multiple PATH variables when using
  secure_path in env.c
  - http://www.sudo.ws/repos/sudo/raw-rev/a09c6812eaec
  - CVE-2010-1646

36. By Jamie Strandboge on 2010-04-07

* SECURITY UPDATE: properly verify path in find_path.c for the 'sudoedit'
  pseudo-command when running from the current working directory and
  secure_path is disabled
  - CVE-2010-XXXX

35. By Martin Pitt on 2010-03-26

env.c: Revert addition of "http_proxy" again. This was an Ubuntu specific
EBW hack, caused inconsistencies with other proxy variables (such as
https_proxy and ftp_proxy), made sudo incompatible to upstream
behaviour/documentation. This is solved in a much better way in apt itself
and gnome-network-properties now. (LP: #432631)

34. By Marc Deslauriers on 2010-03-07

debian/sudo.postinst, debian/sudo-ldap.postinst: update description to
match behaviour in sudoers file. (LP: #534090)
