Synopsis
The remote Red Hat host is missing one or more security updates for firefox.
Description
The remote Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2005:383 advisory.
Mozilla Firefox is an open source Web browser.
Vladimir V. Perepelitsa discovered a bug in the way Firefox handles anonymous functions during regular expression string replacement. It is possible for a malicious web page to capture a random block of browser memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0989 to this issue.
Omar Khan discovered a bug in the way Firefox processes the PLUGINSPAGE tag. It is possible for a malicious web page to trick a user into pressing the manual install button for an unknown plugin leading to arbitrary javascript code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0752 to this issue.
Doron Rosenberg discovered a bug in the way Firefox displays pop-up windows. If a user choses to open a pop-up window whose URL is malicious javascript, the script will be executed with elevated privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1153 to this issue.
A bug was found in the way Firefox handles the javascript global scope for a window. It is possible for a malicious web page to define a global variable known to be used by a different site, allowing malicious code to be executed in the context of the site. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1154 to this issue.
Michael Krax discovered a bug in the way Firefox handles favicon links. A malicious web page can programatically define a favicon link tag as javascript, executing arbitrary javascript with elevated privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1155 to this issue.
Michael Krax discovered a bug in the way Firefox installed search plugins.
If a user chooses to install a search plugin from a malicious site, the new plugin could silently overwrite an existing plugin. This could allow the malicious plugin to execute arbitrary code and steal sensitive information.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-1156 and CAN-2005-1157 to these issues.
Kohei Yoshino discovered a bug in the way Firefox opens links in its sidebar. A malicious web page could construct a link in such a way that, when clicked on, could execute arbitrary javascript with elevated privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1158 to this issue.
A bug was found in the way Firefox validated several XPInstall related javascript objects. A malicious web page could pass other objects to the XPInstall objects, resulting in the javascript interpreter jumping to arbitrary locations in memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1159 to this issue.
A bug was found in the way the Firefox privileged UI code handled DOM nodes from the content window. A malicious web page could install malicious javascript code or steal data requiring a user to do commonplace actions such as clicking a link or opening the context menu. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1160 to this issue.
Users of Firefox are advised to upgrade to this updated package which contains Firefox version 1.0.3 and is not vulnerable to these issues.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL firefox package based on the guidance in RHSA-2005:383.
