Mandrakelinux Security Update Advisory

 Package name:           utempter
 Advisory ID:            MDKSA-2004:031-1
 Date:                   April 21st, 2004
 Original Advisory Date: April 19th, 2004
 Affected versions:	 10.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2

 Problem Description:

 Steve Grubb discovered two potential issues in the utempter program:
 1) If the path to the device contained /../ or /./ or //, the                 
 program was not exiting as it should. It would be possible to use something 
 like /dev/../tmp/tty0, and then if /tmp/tty0 were deleted and symlinked 
 to another important file, programs that have root privileges that do no 
 further validation can then overwrite whatever the symlink pointed to.
 2) Several calls to strncpy without a manual termination of the string.
 This would most likely crash utempter.
 The updated packages are patched to correct these problems.

 The second portion of the patch to address the manual termination of 
 the string has been determined to be uneccessary, as well as reducing the 
 length of utmp strings by one character.  As such, it has been removed.
