(ZEO) improperly filtered certain commands when a database is shared among
multiple applications or application instances. A remote attacker could
send malicious commands to the server and execute arbitrary code.
(CVE-2009-0668)

It was discovered that the Zope Object Database (ZODB) database server
(ZEO) did not handle authentication properly when a database is shared
among multiple applications or application instances. A remote attacker
could use this flaw to bypass security restrictions. (CVE-2009-0669)

It was discovered that Zope did not limit the number of new object ids a
client could request. A remote attacker could use this flaw to consume a
huge amount of resources, leading to a denial of service. (No CVE
identifier)
