Scientific Linux Security Update : firefox on SL5.x, SL6.x i386/x86_64

Critical Nessus Plugin ID 72322


The remote Scientific Linux host is missing one or more security updates.


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-2014-1477, CVE-2014-1482, CVE-2014-1486)

A flaw was found in the way Firefox handled error messages related to web workers. An attacker could use this flaw to bypass the same-origin policy, which could lead to cross-site scripting (XSS) attacks, or could potentially be used to gather authentication tokens and other data from third-party websites. (CVE-2014-1487)

A flaw was found in the implementation of System Only Wrappers (SOW).
An attacker could use this flaw to crash Firefox. When combined with other vulnerabilities, this flaw could have additional security implications. (CVE-2014-1479)

It was found that the Firefox JavaScript engine incorrectly handled window objects. A remote attacker could use this flaw to bypass certain security checks and possibly execute arbitrary code.

After installing the update, Firefox must be restarted for the changes to take effect.


Update the affected firefox and / or firefox-debuginfo packages.
