                 Mandriva Linux Security Update Advisory
  _______________________________________________________________________

  Package name:           sudo
  Advisory ID:            MDKSA-2005:103
  Date:                   June 21st, 2005

  Affected versions:	 10.0, 10.1, 10.2, Corporate 3.0,
			 Corporate Server 2.1
  ______________________________________________________________________

  Problem Description:

  A race condition was discovered in sudo by Charles Morris.  This could
  lead to the escalation of privileges if /etc/sudoers allowed a user to
  execute selected programs that were then followed by another line
  containing the pseudo-command "ALL".  By creating symbolic links at a
  certain time, that user could execute arbitrary commands.

  The updated packages have been patched to correct this problem.
