Scientific Linux Security Update : firefox on SL5.x, SL6.x i386/x86_64
High Nessus Plugin ID 61282
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionMozilla Firefox is an open source web browser.
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-2012-0461, CVE-2012-0462, CVE-2012-0464)
Two flaws were found in the way Firefox parsed certain Scalable Vector Graphics (SVG) image files. A web page containing a malicious SVG image file could cause an information leak, or cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0456, CVE-2012-0457)
If a user were tricked into setting such a home page by dragging a link to the home button, it could cause Firefox to repeatedly crash, eventually leading to arbitrary code execution with the privileges of the user running Firefox. (CVE-2012-0458)
A flaw was found in the way Firefox parsed certain web content containing 'cssText'. 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-2012-0459)
It was found that by using the DOM fullscreen API, untrusted content could bypass the mozRequestFullscreen security protections. A web page containing malicious web content could exploit this API flaw to cause user interface spoofing. (CVE-2012-0460)
A flaw was found in the way Firefox handled pages with multiple Content Security Policy (CSP) headers. This could lead to a cross-site scripting attack if used in conjunction with a website that has a header injection flaw. (CVE-2012-0451)
For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.3 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.
This update also fixes the following bugs :
- When using the Traditional Chinese locale (zh-TW), a segmentation fault sometimes occurred when closing Firefox.
- Inputting any text in the Web Console (Tools -> Web Developer -> Web Console) caused Firefox to crash.
All Firefox users should upgrade to these updated packages, which contain Firefox version 10.0.3 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.
SolutionUpdate the affected packages.
