Description William Hooper 2003-09-17 01:44:22 UTC
Description of problem:
It looks like more issues were found after the release of OpenSSH 3.7 (and RHSA-
2003:279).

Quote:

Security Changes:
=================

  All versions of OpenSSH's sshd prior to 3.7.1 contain buffer
  management errors.  It is uncertain whether these errors are
  potentially exploitable, however, we prefer to see bugs
  fixed proactively.

  OpenSSH 3.7 fixed one of these bugs.

  OpenSSH 3.7.1 fixes more similar bugs.


Version-Release number of selected component (if applicable):

Comment 1 Seth Vidal 2003-09-17 04:57:07 UTC
http://www.openssh.com/txt/buffer.adv

the first patch listed here is needed for the packages in rhl 7.x, 8.0 and 9.

At the time the patched packages were pushed from red hat today the above patch
wasn't out yet.

I've just built some packages with the above patch applied, they appear to check
out normally in my rudimentary QA.

I'd attach a src.rpm but the change is trivial


Comment 2 Seth Vidal 2003-09-17 06:28:01 UTC
Created attachment 94548 [details]
patch for 7.x building

This is the modifications to the new patches from the advisories for rhl 7.x
systems.

I've tested this on 7.3. It should work on 7.2 and 7.1.

packages built and tested from this appear to be happy.

Comment 3 Mark J. Cox 2003-09-17 07:55:58 UTC
I've allocated CAN-2003-0695 to these additional fixes and we're working on
updating our package sets.

http://www.openpkg.org/security/OpenPKG-SA-2003.040-openssh.html

This page claims there are *four* more OpenSSH holes (and claims to have
corrected packages).

Comment 6 Barry K. Nathan 2003-09-17 18:46:41 UTC
Following up on my previous comment, another patch; I'm guessing it applies to
OpenSSH 3.7.1p1 but I haven't tried applying it yet:
http://cvs.openpkg.org/chngview?cn=12268

I think other branches of OpenPKG CVS have patches against older OpenSSH versions.

Comment 7 Seth Vidal 2003-09-17 22:35:11 UTC
Just a note: Wanted to thank the red hat security/openssh people for getting to
this so quickly.

If you find your way near duke univ I'll be glad to buy you all a $beverage.



Comment 8 Mark J. Cox 2003-09-18 10:07:05 UTC
Our update was released yesterday and included the additional fixes from Solar
Designer.
