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-2014-1547, CVE-2014-1555, CVE-2014-1556, CVE-2014-1557)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, David Keeler, Byron Campen, Jethro Beekman, Patrick Cozzi, and Mozilla community member John as the original reporters of these issues.
