CVE-2017-9797 Apache Geode client/server authentication vulnerability

Severity: Medium
CVSS Base Score 6.5 (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H)

Vendor: The Apache Software Foundation

Versions Affected:
Apache Geode 1.0.0 through 1.2.0

When a cluster is operating in secure mode, an unauthenticated client
can enter multi-user authentication mode and send metadata messages.
These metadata operations could leak information about application
data types.  In addition, an attacker could perform a denial of
service attack on the cluster.

Users of the affected versions should upgrade to Apache Geode 1.2.1 or later.

This issue was reported responsibly to the Apache Geode Security Team
by Dan Smith from Pivotal.
