==================================================================== Red Hat Security Advisory Synopsis: Critical: firefox security update Advisory ID: RHSA-2009:1095-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1095.html Issue date: 2009-06-11 CVE Names: CVE-2009-1392 CVE-2009-1832 CVE-2009-1833 CVE-2009-1834 CVE-2009-1835 CVE-2009-1836 CVE-2009-1837 CVE-2009-1838 CVE-2009-1839 CVE-2009-1840 CVE-2009-1841 ==================================================================== 1. Summary: Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having critical security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: 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 as the user running Firefox. (CVE-2009-1392, CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838, CVE-2009-1841) Multiple flaws were found in the processing of malformed, local file content. If a user loaded malicious, local content via the file:// URL, it was possible for that content to access other local data. (CVE-2009-1835, CVE-2009-1839) A script, privilege elevation flaw was found in the way Firefox loaded XML User Interface Language (XUL) scripts. Firefox and certain add-ons could load malicious content when certain policy checks did not happen. (CVE-2009-1840) A flaw was found in the way Firefox displayed certain Unicode characters in International Domain Names (IDN). If an IDN contained invalid characters, they may have been displayed as spaces, making it appear to the user that they were visiting a trusted site. (CVE-2009-1834) A flaw was found in the way Firefox handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Firefox instance that is using a proxy server, they may be able to steal sensitive information from the site the user is visiting. (CVE-2009-1836) For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.11. You can find a link to the Mozilla advisories in the References section of this errata. All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.11, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5.
