Amazon Linux AMI Security Advisory: ALAS-2014-410
Advisory Release Date: 2014-09-17 21:47 Pacific
Advisory Updated Date: 2014-09-19 12:09 Pacific
Apache Commons HttpClient 3.x, as used in Amazon Flexible Payments Service (FPS) merchant Java SDK and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
It was found that the fix for CVE-2012-6153 was incomplete: the code added to check that the server hostname matches the domain name in a subject's Common Name (CN) field in X.509 certificates was flawed. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate.
