SecurityTracker URL:  http://securitytracker.com/id/1034721
CVE Reference:   CVE-2015-1793   (Links to External Site)
Date:  Jan 20 2016
Impact:   Modification of authentication information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6000 Ethernet Switched NEM 24P 10GE
Description:   A vulnerability was reported in OpenSSL. A remote user can bypass certificate validation on the target system. Sun Blade is affected.

When the validation of a certificate chain fails, the system attempts to validate an alternate certificate chain but does not check the CA flag of untrusted certificates. As a result, a remote user can cause the target system to validate an invalid certificate using a valid leaf certificate.

Applications that verify certificates are affected.

SSL/TLS/DTLS clients and SSL/TLS/DTLS servers using client authentication are affected.

The vendor was notified on June 24, 2015.

Adam Langley/David Benjamin (Google/BoringSSL) reported this vulnerability.

Impact:   A remote user can bypass certificate validation on the target system.
Solution:   Oracle has issued a fix for CVE-2015-1793 for Sun Blade 6000 Ethernet Switched NEM 24P 10GE as part of the January 2016 Oracle Critical Patch Update.

The Oracle Switch ES1-24 and Sun Network 10GE Switch 72p are also affected and fixed by this update.
