 Mandriva Linux Security Advisory                         MDKSA-2006:159
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : sudo
 Date    : August 31, 2006
 Affected: 2006.0, Corporate 3.0, Multi Network Firewall 2.0
 _______________________________________________________________________
 
 Problem Description:
 
 Previous sudo updates were made available to sanitize certain
 environment variables from affecting a sudo call, such as
 PYTHONINSPECT, PERL5OPT, etc.  While those updates were effective in
 addressing those specific environment variables, other variables that
 were not blacklisted were being made available.
 
 Debian addressed this issue by forcing sudo to use a whitlist approach
 in DSA-946-2 by arbitrarily making env_reset the default (as opposed
 to having to be enabled in /etc/sudoers).  Mandriva has opted to follow
 the same approach so now only certain variables are, by default, made
 available, such as HOME, LOGNAME, SHELL, TERM, DISPLAY, XAUTHORITY,
 XAUTHORIZATION, LANG, LANGUAGE, LC_*, and USER, as well as the SUDO_*
 variables.
 
 If other variables are required to be kept, this can be done by editing
 /etc/sudoers and using the env_keep option, such as:
 
     Defaults env_keep="FOO BAR"
 
 As well, the Corporate 3 packages are now compiled with the SECURE_PATH
 setting.
 
 Updated packages are patched to address this issue.
