Description Agostino Sarubbo gentoo-dev 2013-02-12 14:38:31 UTC
From ${URL} :

Originally, Common Vulnerabilities and Exposures assigned an identifier CVE-2012-5783 to the 
following vulnerability:

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.

Later it was found, that the SSL hostname verifier implementation (CVE-2012-5783 fix) contained a 
bug in wildcard matching:
[1] https://issues.apache.org/jira/browse/HTTPCLIENT-1255

which still allowed certain type of certificates checks to pass, even if they shouldn't.

Relevant upstream patches:
