CESA-2007:0097: firefox security update



Updated firefox packages that fix several security bugs are now available for CentOS Linux 5. This update has been rated as having critical security impact by the Red Hat Security Response Team.

Mozilla Firefox is an open source Web browser. Flaws were found in the way Firefox executed malformed JavaScript code. A malicious web page could cause Firefox to crash or allow arbitrary code to be executed as the user running Firefox. (CVE-2007-0775, CVE-2007-0777) Cross-site scripting (XSS) flaws were found in Firefox. A malicious web page could display misleading information, allowing a user to unknowingly divulge sensitive information, such as a password. (CVE-2006-6077, CVE-2007-0995, CVE-2007-0996) A flaw was found in the way Firefox processed JavaScript contained in certain tags. A malicious web page could cause Firefox to execute JavaScript code with the privileges of the user running Firefox. (CVE-2007-0994) A flaw was found in the way Firefox cached web pages on the local disk. A malicious web page may have been able to inject arbitrary HTML into a browsing session if the user reloaded a targeted site. (CVE-2007-0778) Certain web content could overlay Firefox user interface elements such as the hostname and security indicators. A malicious web page could trick a user into thinking they were visiting a different site. (CVE-2007-0779) Two flaws were found in Firefox's displaying of blocked popup windows. If a user could be convinced to open a blocked popup, it was possible to read arbitrary local files, or conduct a cross-site scripting attack against the user. (CVE-2007-0780, CVE-2007-0800) Two buffer overflow flaws were found in the Network Security Services (NSS) code for processing the SSLv2 protocol. Connecting to a malicious secure web server could cause the execution of arbitrary code as the user running Firefox. (CVE-2007-0008, CVE-2007-0009) A flaw was found in the way Firefox handled the "location.hostname" value. A malicious web page could set domain cookies for an arbitrary site, or possibly perform a cross-site scripting attack. (CVE-2007-0981) Users of Firefox are advised to upgrade to this erratum package, containing Firefox version which is not vulnerable to these issues.
