Description Mark J. Cox 2003-09-16 13:48:24 UTC
A bug has been found in the buffer code in OpenSSH.  It is not yet clear if this
could be exploited by an attacker but several possible attack vectors are under
evaluation.  A patch from the OpenBSD team is available.

RHSA-2003:279 in progress.

Comment 2 Seth Vidal 2003-09-16 14:17:59 UTC
Have y'all patched anything else that was not included in this patch:
http://www.freebsd.org/cgi/cvsweb.cgi/src/crypto/openssh/buffer.c.diff?r1=1.1.1.6&r2=1.1.1.7&f=u

?

Just trying to find out if pushing what I have is sufficient or if there is
something else announced privately that I'm missing.

thanks

According to a message posted to openbsd-misc by Markus Friedl
<markus> that's enough:

Created attachment 94524 [details]
patch for openssh 3.1 systems like rhl 7.X

patch for openssh 3.1 systems like rhl 7.x - the provided patch from friedl
just needed a little modfication.

I know something like this will be in red hat's errata but can't hurt to add it
here for others.

Comment 8 Michael Young 2003-09-17 08:09:32 UTC
Are you aware that openssh have revised their advisory and released 3.7.1 - it
looks like they are fixing the problem in more cases.

Comment 9 Mark J. Cox 2003-09-17 08:12:32 UTC
See bug 104551 for these additional issues.
