Comment: This bulletin contains three (3) Apache security advisories.
- --------------------------BEGIN INCLUDED TEXT--------------------
CVE-2017-15693 Apache Geode unsafe deserialization of application objects
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: Apache Geode 1.0.0 through 1.3.0
Description:
The Geode server stores application objects in serialized form.
Certain cluster operations and API invocations cause these objects to
be deserialized. An user with DATA:WRITE access to the cluster may be
able to cause remote code execution if certain classes are present on
the classpath.
Mitigation:
Users of the affected versions should upgrade to Apache Geode 1.4.0 or
later. In addition, users should set the flags
validate-serializable-objects and serializable-object-filter.
Credit:
This issue was reported responsibly to the Apache Geode Security Team
by Man Yue Mo from Semmle.

CVE-2017-15692 Apache Geode unsafe deserialization in TcpServer
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: Apache Geode 1.0.0 through 1.3.0
Description:
The TcpServer within the Geode locator opens a network port that
deserializes data. If an unprivileged user gains access to the Geode
locator, they may be able to cause remote code execution if certain
classes are present on the classpath.
A malicious user can send a network message to the Geode locator and
execute code if certain classes are present on the classpath.
Mitigation:
Users of the affected versions should upgrade to Apache Geode 1.4.0 or
later. In addition, users should set the flag
validate-serializable-objects.

- --------------------------------------------------------------------------------
CVE-2017-15696 Apache Geode configuration request authorization vulnerability
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: Apache Geode 1.0.0 through 1.3.0
Description:
The Geode configuration service does not properly authorize
configuration requests. This allows an unprivileged user who gains
access to the Geode locator to extract configuration data and
previously deployed application code.
Mitigation:
Users of the affected versions should upgrade to Apache Geode 1.4.0 or later.
