Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2015-4513, CVE-2015-7189, CVE-2015-7194, CVE-2015-7196, CVE-2015-7198, CVE-2015-7197)

A same-origin policy bypass flaw was found in the way Firefox handled certain cross-origin resource sharing (CORS) requests. A web page containing malicious content could cause Firefox to disclose sensitive information. (CVE-2015-7193)

A same-origin policy bypass flaw was found in the way Firefox handled URLs containing IP addresses with white-space characters. This could lead to cross-site scripting attacks. (CVE-2015-7188)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, and Gary Kwong, Michal Bentkowski, Looben Yang, Shinto K Anto, Gustavo Grieco, Vytautas Staraitis, Ronald Crane, and Ehsan Akhgari as the original reporters of these issues.
