Mozilla Firefox is an open source web browser.
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-2014-1518, CVE-2014-1524, CVE-2014-1529, CVE-2014-1531)
A use-after-free flaw was found in the way Firefox resolved hosts in certain circumstances. An attacker could use this flaw to crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2014-1532)
An out-of-bounds read flaw was found in the way Firefox decoded JPEG images. Loading a web page containing a specially crafted JPEG image could cause Firefox to crash. (CVE-2014-1523)
A flaw was found in the way Firefox handled browser navigations through history. An attacker could possibly use this flaw to cause the address bar of the browser to display a web page name while loading content from an entirely different web page, which could allow for cross-site scripting (XSS) attacks. (CVE-2014-1530)
