Synopsis
========

Pound is vulnerable to a buffer overflow that could lead to the remote
execution of arbitrary code.

Background
==========

Pound is a reverse proxy, load balancer and HTTPS front-end.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  www-servers/pound       < 1.8.3                          >= 1.8.3

Description
===========

Steven Van Acker has discovered a buffer overflow vulnerability in the
"add_port()" function in Pound.

Impact
======

A remote attacker could send a request for an overly long hostname
parameter, which could lead to the remote execution of arbitrary code
with the rights of the Pound daemon process (by default, Gentoo uses
the "nobody" user to run the Pound daemon).

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Pound users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/pound-1.8.3"

Please tell us whether we are affected and if so start fixing the package.

Comment 2 Marcus Meissner 2005-06-03 09:04:06 UTC 
ping
Comment 3 Joachim Werner 2005-06-03 09:32:36 UTC 
Pound is on 9.2 and 9.3.  
  
I'd suggest to update to 1.9 for both. I don't expect any compatibility issues 
with that.
Comment 4 Ludwig Nussel 2005-06-03 10:05:50 UTC 
Did you actually look at the code? It's a one line fix, no version update for 
that one.
Comment 5 Ludwig Nussel 2005-06-03 10:08:09 UTC 
Created attachment 38585 [details]
pound-1.8.2-CAN-2005-1391.diff

stripped diff 1.8.2->1.8.3. Only the last hunk is the security fix
(CAN-2005-1391). The first two are bugfixes and probably make sense.

The -1 is not needed in snprintf but upsteam fixed it that way.
Comment 6 Ludwig Nussel 2005-06-03 10:10:19 UTC 
SM-Tracker-1456
Comment 7 Joachim Werner 2005-06-05 21:22:29 UTC 
I've submitted the version update for STABLE. 
 
Verified with author that the one-line patch is all we need to fix the issue. 
 
I'll submit patched packages for SL 9.2/9.3. aj doesn't want the version 
upgrade for those.
Comment 8 Joachim Werner 2005-06-05 21:53:30 UTC 
Submitted packages for SL 9.2/9.3. I did mbuild both on the corresponding 
distro, but it wouldn't hurt if someone double-checked if the packages are ok, 
as this is my first security fix. ;-)
Comment 9 Ludwig Nussel 2005-06-06 06:56:45 UTC 
The sad truth is that noone is going to test it.
