| Description: | 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 terminate unexpectedly or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-5590, CVE-2013-5597, CVE-2013-5599, CVE-2013-5600, CVE-2013-5601, CVE-2013-5602)
It was found that the Firefox JavaScript engine incorrectly allocated memory for certain functions. An attacker could combine this flaw with other vulnerabilities to execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-5595)
A flaw was found in the way Firefox handled certain Extensible Stylesheet Language Transformations (XSLT) files. An attacker could combine this flaw with other vulnerabilities to execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-5604)
Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jesse Ruderman, Christoph Diehl, Dan Gohman, Byoungyoung Lee, Nils, and Abhishek Arya as the original reporters of these issues.
