| Description: | Summary:
The remote host is missing an update for the 'firefox'
package(s) announced via the referenced advisory.
Vulnerability Insight:
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-2015-7201, CVE-2015-7205, CVE-2015-7210, CVE-2015-7212,
CVE-2015-7213, CVE-2015-7222)
A flaw was found in the way Firefox handled content using the 'data:' and
'view-source:' URIs. An attacker could use this flaw to bypass the
same-origin policy and read data from cross-site URLs and local files.
(CVE-2015-7214)
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Andrei Vaida, Jesse Ruderman, Bob Clary, Looben Yang,
