Draft announcement:
- DRAFT - XXX - DRAFT -
fetchmail-SA-2010-02: Denial of service in debug mode w/ multichar locales
Topics: Denial of service in debug output.
Author: Matthias Andree
Version: 0.1 XXX
Announced: XXX
Type: malloc() Buffer overrun with printable characters
Impact: Denial of service.
Danger: low
CVE Name: CVE-2010-XXXX
CVSSv2: XXX
URL: http://www.fetchmail.info/fetchmail-SA-2010-02.txt
Project URL: http://www.fetchmail.info/
Affects: fetchmail releases 4.6.3 up to and including 6.3.16
Not affected: fetchmail release 6.3.17 and newer
Corrected: 2010-04-18 Git (XXX)
0. Release history
==================
2010-04-18 0.1 first draft (visible in SVN and through oss-security)
XXX
1. Background
=============
fetchmail is a software package to retrieve mail from remote POP2, POP3,
IMAP, ETRN or ODMR servers and forward it to local SMTP, LMTP servers or
message delivery agents. It supports SSL and TLS security layers through
the OpenSSL library, if enabled at compile time and if also enabled at
run time.
2. Problem description and Impact
=================================
In debug mode (-v -v), fetchmail prints information that was obtained from
the
upstream server (POP3 UIDL lists) or from message headers retrieved from
it.
If printing such information fails, for instance because there are
invalid
multibyte character sequences in this information (message headers),
fetchmail
will misinterpret this condition, and believe that the buffer was too
small,
and reallocate a bigger one (with linearly increasing buffer size), and
repeat,
until the allocation fails. At that point, fetchmail will abort.
Note that the "Affects:" line above may be inaccurate, and it may be that
versions before 5.6.6 are actually unaffected. The author was unable to
compile such old fetchmail versions to verify the existence of the bug.
Given that other security issues are present in such versions, those
should
not be used, and the wider version range was listed as vulnerable to err
towards the safe.
3. Solution
===========
There are two alternatives, either of them by itself is sufficient:
a. Apply the patch found in section B of this announcement to
fetchmail 6.3.14 or newer, recompile and reinstall it.
b. Install fetchmail 6.3.17 or newer after it will have become available.
The fetchmail source code is always available from
<http://developer.berlios.de/project/showfiles.php?group_id=1824>.
4. Workaround
=============
Run fetchmail with at most one -v (--verbose) option.

I had a openSUSE 11.4 i586 installation on one machine, and as I was upgrading
its hardware to a 64-bit CPU, I did a x86_64 reinstall, and copied over the
configs from the previous install. Among that was /etc/ssh/sshd_config.
After this, sftp was no longer usable ("Connection closed by host"), hinting
towards the helper not being executable. sshd_config, having been inherited
from a i586 environment, contained:
Subsystem sftp /usr/lib/ssh/sftp-server
However, the sftp helper was installed in /usr/lib64/ssh (%_libdir/ssh), which
I consider the wrong place, because the helper is bitness-independent and thus
should go to %_libexecdir/ssh instead.
The problem persists by looking at the current /network/openssh/openssh.spec.

Some packages, such as openssh, do explicitly specify a UID/GID when creating
its users/groups:
/usr/sbin/groupadd -g 65 -o -r sshd 2>/dev/null || :;
On the other hand, the hal package does not:
/usr/sbin/groupadd -r haldaemon 2>/dev/null || :
So, which is correct? Should not hal also use a fixed ID? There are many
packages belonging to the latter category.

Whenever i tried to setup a chroot environment with OpenSSH the security
settings for the user folder must be root or OpenSSH doesn't work, the only
solution for now is to either create subfolders in the users chroot folder
where the user can have write permissions or land them one step up in the
hierarchy and thus making them see other chroot folder which is not good.
I followed this Wiki page to the letter:
http://en.opensuse.org/Openssh#SFTP_chroot_with_ChrootDirectory
I have Swedish community users trying to set this up to with same result as me.
This thread takes up the same issue:
http://marc.info/?l=openssh-unix-dev&m=122640731518850&w=2
But the solution mentioned there is not acceptable because as it stats on the
Wiki you make one folder the chroot folder and then mapping the users home
folder relative to the chroot folder, in this scenario the users should get
write permissions to his own folder, but that is not possible, thus breaking
the functionality intended.
So the question is, is this a bug or is it designed to act like this?
Reproducible: Always
Steps to Reproduce:
Done accordingly to this wiki entry: http://en.opensuse.org/OpenSSH
Actual Results:
Gets a read only home folder root
Expected Results:
Getting a writable home folder, where they can create on folder and upload
files directly to the root of their home folder.

If you build a go binary (not a package) you include Make.cmd instead of
Make.pkg.
Make.pkg installs in TARGDIR, which is set by the macro: %{go_make_install} to
TARGDIR=%{buildroot}%{go_sitearch}
This is right, as Make.pkg sets it as default to
$(GOROOT)/pkg/$(GOOS)_$(GOARCH)
But if you build a command, Make.cmd uses $GOBIN (/usr/bin), but it gets
overriden by %{go_make_install} resulting in the binary to be installed in the
package directory.

When you disable ipv6 from the yast2 network, system correctly remove the
assignation of ipv6 addresses from everywhere but there is an annoying bug in
openssh that break the possibility to make X11 tunnels because it seems that
ssh try to bind X11 tunnel to an ipv6 address even with ipv6 disabled causing
this kind of message in /var/log/messages:
Aug 17 16:47:28 franz2011 sshd[6300]: error: Failed to allocate internet-domain
X11 display socket.
this can avoided configuring correctly the file /etc/ssh/sshd_config with the
parameter:
AddressFamily inet
and restarting sshd.
