SuSE Security Announcement
Package: rsync-2.2.1 and previous
Date: Tue Aug 25 07:45:15 CEST 1999
Affected: all Linux distributions using rsync
______________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update as soon as possible or disable the service if you are using
this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected as
well, please contact your vendor for information about this issue.
Please note, that that we provide this information on as "as-is" basis only.
There is no warranty whatsoever and no liability for any direct, indirect or
incidental damage arising from this information or the installation of
the update package.
_____________________________________________________________________________
1. Problem Description
The security breach occurs when you try to transfer an empty
directory into a non-existent directory.
In that case rsync sets the permissions of the working directory
to those of the empty directory; this means, that the permissions
of your home directory are changed to the file access mode of the
empty directory if you do a remote rsync by using ssh/rsh.
2. Impact
If an attacker is successful in exploiting this bug, s/he could gain
access to protected files in a users home directory.
This could lead to local root compromise, i.e. by modifying the PATH
environment variable and smuggleing tronjan horse programs in the
admins home directory or elsewhere.
3. Solution
Updated the rsync package from our FTP server.
