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-2014-1477, CVE-2014-1482, CVE-2014-1486)
A flaw was found in the way Firefox handled error messages related to
web workers. An attacker could use this flaw to bypass the same-origin
policy, which could lead to cross-site scripting (XSS) attacks, or
could potentially be used to gather authentication tokens and other
data from third-party websites. (CVE-2014-1487)
A flaw was found in the implementation of System Only Wrappers (SOW).
An attacker could use this flaw to crash Firefox. When combined with
other vulnerabilities, this flaw could have additional security
window objects. A remote attacker could use this flaw to bypass
certain security checks and possibly execute arbitrary code.
