CVE-2014-3577 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-3577): org.apache.http.conn.ssl.AbstractVerifier in Apache HttpComponents HttpClient before 4.3.5 and HttpAsyncClient before 4.0.2 does not properly 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 a "CN=" string in a field in the distinguished name (DN) of a certificate, as demonstrated by the "foo,CN=www.apache.org" string in the O field. +*httpcomponents-core-4.4.1 (19 Jun 2015) + + 19 Jun 2015; Patrice Clement <monsieurp@gentoo.org> + +files/httpcomponents-core-4.4.1-httpcore-build.xml, + +files/httpcomponents-core-4.4.1-httpcore-nio-build.xml, + +httpcomponents-core-4.4.1.ebuild: + Version bump.

From ${URL}: Apache HttpComponents (prior to revision 4.3.5/4.0.2) may be susceptible to a 'Man in the Middle Attack' due to a flaw in the default hostname verification during SSL/TLS when a specially crafted server side certificate is used. ... Impact: - ------- A man-in-the-middle can interpose itself between the server and the code using an affected version of Apache HttpComponents as a client. Leading to complete loss of end to end confidentiality and end to end integrety of the connection. Versions affected: - ------------------ All versions prior to HttpClient 4.3.5 (including the Android port) and HttpAsyncClient 4.0.2. The fix was introduced in these versions. http://search.maven.org/#artifactdetails|org.apache.httpcomponents| httpclient|4.3.5|jar http://search.maven.org/#artifactdetails|org.apache.httpcomponents| httpasyncclient|4.0.2|jar These have been silently pushed out to Maven central and Apache Dist as of 2014-08-1. An Android build was released on 2014-08-15. Resolution - ---------- A fix has been applied as of revision 1614065 and is part of release HttpClient 4.3.5 (including HttpClient port for Android against the official Google Android SDK)and HttpClient (async) 4.0.2. Upgrading to these versions newer resolves this issue. Mitigations and work arounds - ---------------------------- If upgrading to version 4.3.5/4.0.2 is not an option; one could change the default org.apache.http.conn.ssl.AbstractVerifier of earlier versions for revision 1614065 of newer. Note that exploitation of this flaw also requires some level of DNS or IP spoofing (or existing 'in the middle infrastructure' such as a corporate proxy or other TCP level equipment en-route). This need may allow for site specific alternative mitigations.
