Problem Description:
A problem exists with openssh's scp program. If a user uses scp to move files
from a server that has been compromised, the operation can be used to replace
arbitrary files on the user's system. The problem is made more serious by
setuid versions of ssh which allow overwriting any file on the local user's
system. If the ssh program is not setuid or is setuid to someone other than
root, the intrustion is limited to files with write access granted to the owner
of the ssh program. In either case, files can be overwritten with code allowing
others access to the system unexpectedly. While no fix has been provided for
openssh as of yet, the versions of openssh available for Linux-Mandrake 7.0 and
7.1 were setuid root. This update removes the setuid bit from the ssh program
and limits the exploitability of scp somewhat. All users of Linux-Mandrake are
encouraged to upgrade to these latest openssh builds. Linux-Mandrake 7.0 users
will also need to upgrade openssl in order to use the 7.0 update of openssh.
