Scientific Linux Security Update : firefox on SL5.x, SL6.x i386/x86_64 (20130625)
Critical Nessus Plugin ID 66983
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSeveral 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-2013-1682, CVE-2013-1684, CVE-2013-1685, CVE-2013-1686, CVE-2013-1687, CVE-2013-1690)
It was found that Firefox allowed data to be sent in the body of XMLHttpRequest (XHR) HEAD requests. In some cases this could allow attackers to conduct Cross-Site Request Forgery (CSRF) attacks.
Timing differences in the way Firefox processed SVG image files could allow an attacker to read data across domains, potentially leading to information disclosure. (CVE-2013-1693)
Two flaws were found in the way Firefox implemented some of its internal structures (called wrappers). An attacker could use these flaws to bypass some restrictions placed on them. This could lead to unexpected behavior or a potentially exploitable crash.
0.7 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.
SolutionUpdate the affected packages.
