Mandrake Linux Advisory: util-linux

Feb 14, 2003, 02:59 (0 Talkback[s])

______________________________________________________________________

                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           util-linux
Advisory ID:            MDKSA-2003:016
Date:                   February 13th, 2003

Affected versions:      8.2, 9.0
______________________________________________________________________

Problem Description:

 The util-linux package provides the mcookie utility, a tool for 
 generating random cookies that can be used for X authentication.  The 
 util-linux packages that were distributed with Mandrake Linux 8.2 and 
 9.0 had a patch that made it use /dev/urandom instead of /dev/random, 
 which resulted in the mcookie being more predictable than it would 
 otherwise be.  This patch has been removed in these updates, giving 
 mcookie a better source of entropy and making the generated cookies 
 less predictable.  Thanks to Dirk Mueller for pointing this out.
