Mozilla Firefox before 42.0 on Android allows user-assisted remote attackers to bypass the Same Origin Policy and trigger (1) a download or (2) cached profile-data reading via a file: URL in a saved HTML document.

Versions of Mozilla Firefox for Android earlier than 42.0 are affected by multiple vulnerabilities.  These include : 

 - A flaw exists in 'mobile/android/chrome/content/browser.js' that is triggered when the device exits fullscreen mode. This allows a context-dependent attacker to spoof the address bar. (CVE-2015-7185)
 - A flaw exists in 'mobile/android/components/HelperAppDialog.js' that is triggered when handling the 'file://' URI scheme. This may allow a context-dependent attacker to download arbitrary files or open cached profile data without the user knowing. (CVE-2015-7186)
 - A flaw exists in 'mobile/android/search/java/org/mozilla/search/PostSearchFragment.java' related to the crash reporter. The issue is triggered when a registered search engine uses an Android intent to launch the program. This may allow a malicious app to gain access to local log files that may contain sensitive information or local HTML files through file: URIs. (CVE-2015-7190)
 - A flaw exists in the 'IntentHelper::openNoHandler()' function in 'mobile/android/base/IntentHelper.java.' The issue is triggered when handling 'intent://' URLs during Fallback navigation. This may allow a context-dependent attacker to execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server (i.e. conduct UXSS attacks). (CVE-2015-7191)

  - Install the static libfreebl.a that is needed in order     to link Sun elliptical curves provider in Java 7.

This includes the update of Mozilla NSS to NSS 3.20 New functionality :

  - The TLS library has been extended to support DHE     ciphersuites in server applications. New Functions :

  - SSL_DHEGroupPrefSet - Configure the set of     allowed/enabled DHE group parameters that can be used by     NSS for a server socket.

  - SSL_EnableWeakDHEPrimeGroup - Enable the use of weak DHE     group parameters that are smaller than the library     default's minimum size. New Types :

  - SSLDHEGroupType - Enumerates the set of DHE parameters     embedded in NSS that can be used with function     SSL_DHEGroupPrefSet. New Macros :

  - SSL_ENABLE_SERVER_DHE - A socket option user to enable     or disable DHE ciphersuites for a server socket. Notable     Changes :

  - For backwards compatibility reasons, the server side     implementation of the TLS library keeps all DHE     ciphersuites disabled by default. They can be enabled     with the new socket option SSL_ENABLE_SERVER_DHE and the     SSL_OptionSet or the SSL_OptionSetDefault API.

  - The server side implementation of the TLS implementation     does not support session tickets when using a DHE     ciphersuite (see bmo#1174677).

  - Support for the following ciphersuites has been added :

  - TLS_DHE_DSS_WITH_AES_128_GCM_SHA256

  - TLS_DHE_DSS_WITH_AES_128_CBC_SHA256

  - TLS_DHE_DSS_WITH_AES_256_CBC_SHA256

  - By default, the server side TLS implementation will use     DHE parameters with a size of 2048 bits when using DHE     ciphersuites.

  - NSS embeds fixed DHE parameters sized 2048, 3072, 4096,     6144 and 8192 bits, which were copied from version 08 of     the Internet-Draft 'Negotiated Finite Field     Diffie-Hellman Ephemeral Parameters for TLS', Appendix     A.

  - A new API SSL_DHEGroupPrefSet has been added to NSS,     which allows a server application to select one or     multiple of the embedded DHE parameters as the preferred     parameters. The current implementation of NSS will     always use the first entry in the array that is passed     as a parameter to the SSL_DHEGroupPrefSet API. In future     versions of the TLS implementation, a TLS client might     signal a preference for certain DHE parameters, and the     NSS TLS server side implementation might select a     matching entry from the set of parameters that have been     configured as preferred on the server side.

  - NSS optionally supports the use of weak DHE parameters     with DHE ciphersuites to support legacy clients. In     order to enable this support, the new API     SSL_EnableWeakDHEPrimeGroup must be used. Each time this     API is called for the first time in a process, a fresh     set of weak DHE parameters will be randomly created,     which may take a long amount of time. Please refer to     the comments in the header file that declares the     SSL_EnableWeakDHEPrimeGroup API for additional details.

  - The size of the default PQG parameters used by certutil     when creating DSA keys has been increased to use 2048     bit parameters.

  - The selfserv utility has been enhanced to support the     new DHE features.

  - NSS no longer supports C compilers that predate the ANSI     C standard (C89).
