RHSA-2012:0387 - Critical: firefox security and bug fix update

Synopsis

Critical: firefox security and bug fix update

Type/Severity

Security Advisory Critical

Topic

Updated firefox packages that fix multiple security issues and three bugs are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Description

Mozilla 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)

A flaw could allow a malicious site to bypass intended restrictions, possibly leading to a cross-site scripting (XSS) attack if a user were tricked into dropping a "javascript:" link onto a frame. (CVE-2012-0455)

It was found that the home page could be set to a "javascript:" link. 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. (BZ#729632)

  • Inputting any text in the Web Console (Tools -> Web Developer -> Web Console) caused Firefox to crash. (BZ#784048)

  • The java-1.6.0-ibm-plugin and java-1.6.0-sun-plugin packages require the "/usr/lib/mozilla/plugins/" directory on 32-bit systems, and the "/usr/lib64/mozilla/plugins/" directory on 64-bit systems. These directories are created by the xulrunner package; however, they were missing from the xulrunner package provided by the RHEA-2012:0327 update. Therefore, upgrading to RHEA-2012:0327 removed those directories, causing dependency errors when attempting to install the java-1.6.0-ibm-plugin or java-1.6.0-sun-plugin package. With this update, xulrunner once again creates the plugins directory. This issue did not affect users of Red Hat Enterprise Linux 6. (BZ#799042)

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.
