                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           rsync
Advisory ID:            MDKSA-2002:024
Date:                   March 13th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, Corporate Server 1.0.1,
                        Single Network Firewall 7.2

Problem Description:

 Ethan Benson discovered a bug in rsync where the supplementary groups
 that the rsync daemon runs as (such as root) would not be removed
 from the server process after changing to the specified unprivileged
 uid and gid.  This seems only serious if rsync is called using "rsync
 --daemon" from the command line where it will inherit the group of the
 user starting the server (usually root).  Note that, by default,
 Mandrake Linux uses xinetd to handle connections to the rsync daemon.
 This was fixed upstream in version 2.5.3, as well as the previously
 noted zlib fixes (see MDKSA-2002:023).  The authors released 2.5.4 with
 some additional zlib fixes, and all users are encouraged to upgrade to
 this new version of rsync.
