Mar 19, 2015 1:45pm CDT: First version


We are aware of the announced vulnerability described in CVE-2015-0291 (ClientHello signalgs DoS). We are investigating the issue and will update this post with more detail as necessary.

Risk Assessment

Our assessment is that the Globus service and the Globus Toolkit are not vulnerable to currently known exploits resulting from this vulnerability.

There are two “Severity: High” issues reported: - CVE-2015-0291 - An attacker could cause a denial of service (DoS) on a vulnerable host. - CVE-2015-0204 - An attacker could cause a man-in-the-middle (MITM) on a vulnerable host.

Actions We Have Taken to Close Attack Vector

No action was required. The versions of OpenSSL Globus service hosts are running are not vulnerable.

We recommend any host with Globus services (e.g. Globus Connect Personal, Globus Connect Server, GridFTP, MyProxy, GSI-OpenSSH, GRAM) to review their host configuration and apply the advised updates if necessary. Please consult your software vendor for latest updates.
