CentOS Errata and Security Advisory CESA-2012:1350
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-2012-3982, CVE-2012-3988, CVE-2012-3990, CVE-2012-3995,
CVE-2012-4179, CVE-2012-4180, CVE-2012-4181, CVE-2012-4182, CVE-2012-4183,
CVE-2012-4185, CVE-2012-4186, CVE-2012-4187, CVE-2012-4188)
Two flaws in Firefox could allow a malicious website to bypass intended
restrictions, possibly leading to information disclosure, or Firefox
executing arbitrary code. Note that the information disclosure issue could
possibly be combined with other flaws to achieve arbitrary code execution.
(CVE-2012-3986, CVE-2012-3991)
Multiple flaws were found in the location object implementation in Firefox.
Malicious content could be used to perform cross-site scripting attacks,
script injection, or spoofing attacks. (CVE-2012-1956, CVE-2012-3992,
CVE-2012-3994)
Two flaws were found in the way Chrome Object Wrappers were implemented.
Malicious content could be used to perform cross-site scripting attacks or
cause Firefox to execute arbitrary code. (CVE-2012-3993, CVE-2012-4184)
For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.8 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.
Red Hat would like to thank the Mozilla project for reporting these issues.
