Shibboleth Security Advisory [08 June 2014]
Updated versions of the OpenSSL library are available that correct
a serious bug that can lead to tampering with, or disclosure of, user
information. While servers are affected only in the latest versions,
clients are affected regardless of library version. As the Shibboleth
SP is an OpenSSL client, many deployments will be affected and may
need to apply patches, or in some cases upgrade to a supported
version of the SP.
Refer to the Recommendations section below for specific guidance on
how particular platforms are affected.
OpenSSL Man in the Middle vulnerability
===================================================================
The OpenSSL team disclosed and patched a security issue that
can expose clients and servers to a Man in the Middle attack
when establishing TLS/SSL connections.
The OpenSSL advisory was assigned CVE-2014-0224 can be found at
http://www.openssl.org/news/secadv_20140605.txt
In the case of Shibboleth, this primarily affects deployments
that rely on SOAP communication, typically SAML 1.1 exchanges
that rely on SAML attribute queries, or the use of SAML 1.1
or SAML 2.0 artifact-based Single Sign-On. Default uses of
SAML 2.0 typically do not involve SOAP over a backchannel,
but queries may be triggered by the delivery of a signed
response from an IdP with no attributes present.
The attack is such that both the confidentiality and integrity
of information exchanged can be compromised, which in the
above scenarios represents a threat of impersonation of users
to applications and of information disclosure. The attack is an
active one that requires real-time interception and modification
of network traffic between systems.
The Shibboleth IdP product is a Java implementation, and as such
does not directly make use of OpenSSL, but is often deployed in
conjunction with Apache as a web server, or may be deployed in
a Java container which is relying on OpenSSL, such as Tomcat's
APR runtime option.
The Shibboleth SP makes direct use of OpenSSL, and in the case of
Microsoft Windows, includes a vulnerable version in both the current
SP version and most or all historical versions.
Recommendations
===============
For Windows installations, a patch [1][2] is now available to update
version 2.5.3 to the latest OpenSSL revision (1.0.1h) to correct the
issue. This patch supersedes the earlier patch produced to address
the Heartbleed issue, and can be installed on top of, or instead of,
that earlier patch, as needed. The older patch has been removed from
the download site.
Older Windows versions containing affected versions need to be
updated to 2.5.3 to apply this patch.
Unlike the recent Heartbleed vulnerability, this issue affects
*all* older releases of OpenSSL, and therefore all older Windows
versions of the Service Provider software are affected. Per our
support policy, there will be no patches produced for unsupported
versions.
The installer for 2.5.3 has been updated to include this patch.
Deployers using other platforms should refer to their OpenSSL
technology provider for an update.
No other updates to the Shibboleth software itself are required to
mitigate this issue.
