    Package        : zope2.10/zope2.9
    Vulnerability  : several
    Problem type   : remote
    Debian-specific: no
    CVE IDs        : CVE-2009-0668 CVE-2009-0669
    
    Several remote vulnerabilities have been discovered in the zope,
    a feature-rich web application server written in python, that could
    lead to arbitrary code execution in the worst case.  The Common
    Vulnerabilities and Exposures project identified the following problems:
    
    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 (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-2009-0668).
    
    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.
    
    
    The oldstable distribution (etch), this problem has been fixed in
    version 2.9.6-4etch2 of zope2.9.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 2.10.6-1+lenny1 of zope2.10.
    
    For the testing distribution (squeeze), this problem will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.10.9-1 of zope2.10.
    
    
    We recommend that you upgrade your zope2.10/zope2.9 packages.
