Description revelant 1999-02-02 03:18:33 UTC
On the website I found the
following info about an exploit

     A smbmount root exploit has been posted to bugtraq.
Apply this patch to your smbmount.c, and recompile is your
smbfs utilities.
     smbfs-2.0.2 has this patch applied.

The version of smbfs in the Red Hat 5.2 dist is 2.0.1-4.
There is no update for smbfs in the errata list at

Could you verify the truth of this (I have not run the
exploit myself) and release an update if appropriate.

Sources can be found at the above web site, although I have
no idea how authoritative they are.

Comment 1 Aleksey Nogin 1999-02-02 06:52:59 UTC
AFAIK, by default smbfs RPM installs smbmount without suid bit set, so
it should not be possible to exploit it.

Comment 2 Bill Nottingham 1999-02-02 16:48:59 UTC
What he said.
smbmount isn't installed suid root, so the bug isn't exploitable
on Red Hat.
