Description

This security bulletin contains information about 1 vulnerability.


1) Security restrictions bypass (CVE-ID: CVE-2016-4467)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass certificate validation on the target system. 

The vulnerability exists due to authentication error in Apache Qpid Proton Library. The Proton C client and C-based client bindings on Windows-based systems improperly verify that the server host name matches the domain name in the certificate's Common Name (CN) or subjectAltName fields.

Applications that use the Proton C library for SSL/TLS authentication on Windows-based systems with the default SChannel-based security layer are affected.


Remediation

Install update from vendor's website.
