Mozilla 1.7.8, Firefox 1.0.4, Camino 0.8.4, Netscape 8.0.2, and K-Meleon 0.9, and possibly other products that use the Gecko engine, allow remote attackers to cause a denial of service (application crash) via JavaScript that repeatedly calls an empty function.

An updated firefox package that fixes various security bugs is now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

Mozilla Firefox is an open source Web browser.

A bug was found in the way Firefox handled synthetic events. It is possible that Web content could generate events such as keystrokes or mouse clicks that could be used to steal data or execute malicious JavaScript code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2260 to this issue.

A bug was found in the way Firefox executed JavaScript in XBL controls. It is possible for a malicious webpage to leverage this vulnerability to execute other JavaScript based attacks even when JavaScript is disabled. (CVE-2005-2261)

A bug was found in the way Firefox set an image as the desktop wallpaper. If a user chooses the 'Set As Wallpaper...' context menu item on a specially crafted image, it is possible for an attacker to execute arbitrary code on a victim's machine. (CVE-2005-2262)

A bug was found in the way Firefox installed its extensions. If a user can be tricked into visiting a malicious webpage, it may be possible to obtain sensitive information such as cookies or passwords.
(CVE-2005-2263)

A bug was found in the way Firefox handled the _search target. It is possible for a malicious website to inject JavaScript into an already open webpage. (CVE-2005-2264)

A bug was found in the way Firefox handled certain JavaScript functions. It is possible for a malicious web page to crash the browser by executing malformed JavaScript code. (CVE-2005-2265)

A bug was found in the way Firefox handled multiple frame domains. It is possible for a frame as part of a malicious website to inject content into a frame that belongs to another domain. This issue was previously fixed as CVE-2004-0718 but was accidentally disabled.
(CVE-2005-1937)

A bug was found in the way Firefox handled child frames. It is possible for a malicious framed page to steal sensitive information from its parent page. (CVE-2005-2266)

A bug was found in the way Firefox opened URLs from media players. If a media player opens a URL that is JavaScript, JavaScript is executed with access to the currently open webpage. (CVE-2005-2267)

A design flaw was found in the way Firefox displayed alerts and prompts. Alerts and prompts were given the generic title [JavaScript Application] which prevented a user from knowing which site created them. (CVE-2005-2268)

A bug was found in the way Firefox handled DOM node names. It is possible for a malicious site to overwrite a DOM node name, allowing certain privileged chrome actions to execute the malicious JavaScript.
(CVE-2005-2269)

A bug was found in the way Firefox cloned base objects. It is possible for Web content to navigate up the prototype chain to gain access to privileged chrome objects. (CVE-2005-2270)

Users of Firefox are advised to upgrade to this updated package that contains Firefox version 1.0.6 and is not vulnerable to these issues.

Updated mozilla packages that fix various security issues are now available.
