Package : zodb
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-0668 CVE-2009-0669
Debian Bug : 540465

Several remote vulnerabilities have been discovered in python-zodb, a set of
tools for using ZODB, that could lead to arbitrary code execution in the worst
case. The Common Vulnerabilities and Exposures project identified the following
problems:

CVE-2009-0668

The ZEO server doesn't restrict the callables when unpickling data
received from a malicious client which can be used by an attacker to execute
arbitrary python code on the server by sending certain exception pickles. This
also allows an attacker to import any importable module as ZEO is importing the
module containing a callable specified in a pickle to test for a certain flag.

CVE-2009-0669

Due to a programming error an authorization method in the StorageServer
component of ZEO was not used as an internal method. This allows a malicious
client to bypass authentication when connecting to a ZEO server by simply
calling this authorization method.

The update also limits the number of new object ids a client can request
to 100 as it would be possible to consume huge amounts of resources by
requesting a big batch of new object ids. No CVE id has been assigned to this.

For the oldstable distribution (lenny), this problem has been fixed in
version 1:3.6.0-2+lenny3.

The stable distribution (squeeze) is not affected, it was fixed before
the initial release.

For the unstable distribution (sid), this problem has been fixed in
version 1:3.8.2-1.

We recommend that you upgrade your zodb packages.

Package : mahara
Vulnerability : several vulnerabilities
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-1402 CVE-2011-1403 CVE-2011-1404 CVE-2011-1405
CVE-2011-1406


Several vulnerabilities were discovered in mahara, an electronic portfolio,
weblog, and resume builder. The following Common Vulnerabilities and
Exposures project ids identify them:


CVE-2011-1402

It was discovered that previous versions of Mahara did not check user
credentials before adding a secret URL to a view or suspending a user.


CVE-2011-1403

Due to a misconfiguration of the Pieform package in Mahara, the cross-site
request forgery protection mechanism that Mahara relies on to harden its
form was not working and was essentially disabled.
This is a critical vulnerability which could allow attackers to trick other
users (for example administrators) into performing malicious actions on
behalf of the attacker. Most Mahara forms are vulnerable.


CVE-2011-1404

Many of the JSON structures returned by Mahara for its AJAX interactions
included more information than what ought to be disclosed to the logged in
user. New versions of Mahara limit this information to what is necessary for
each page.


CVE-2011-1405

Previous versions of Mahara did not escape the contents of HTML emails sent
to users. Depending on the filters enabled in one's mail reader, it could
lead to cross-site scripting attacks.


CVE-2011-1406

It has been pointed out to us that if Mahara is configured (through its
wwwroot variable) to use HTTPS, it will happily let users login via the HTTP
version of the site if the web server is configured to serve content over
both protocol. The new version of Mahara will, when the wwwroot points to an
HTTPS URL, automatically redirect to HTTPS if it detects that it is being
run over HTTP.

We recommend that sites wanting to run Mahara over HTTPS make sure that
their web server configuration does not allow the serving of content over
HTTP and merely redirects to the secure version. We also suggest that site
administrators consider adding the HSTS headers
(http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) to their web
server configuration.


For the oldstable distribution (lenny), these problems have been fixed in
version 1.0.4-4+lenny10.

For the stable distribution (squeeze), these problems have been fixed in
version 1.2.6-2+squeeze2.

For the testing distribution (wheezy), these problems have been fixed in
version 1.3.6-1.

For the unstable distribution (sid), these problems have been fixed in
version 1.3.6-1.

We recommend that you upgrade your mahara packages.

Wouter Coekaerts discovered that ejabberd, a distributed XMPP/Jabber server
written in Erlang, is vulnerable to the so-called "billion laughs" attack
because it does not prevent entity expansion on received data.
This allows an attacker to perform denial of service attacks against the
service by sending specially crafted XML data to it.


For the oldstable distribution (lenny), this problem has been fixed in
version 2.0.1-6+lenny3.

For the stable distribution (squeeze), this problem has been fixed in
version 2.1.5-3+squeeze1.

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 2.1.6-2.1.


We recommend that you upgrade your ejabberd packages.
