Product : Fedora Core 3 Name : firefox Version : 1.0.7 Release : 1.1.fc3 Summary : Mozilla Firefox Web browser. Description : Mozilla Firefox is an open-source web browser, designed for standards compliance, performance and portability.
--------------------------------------------------------------------- Update Information:
An updated firefox package that fixes several security bugs is now available for Fedora Core 3.
This update has been rated as having critical security impact by the Fedora Security Response Team.
Mozilla Firefox is an open source Web browser.
A bug was found in the way Firefox processes XBM image files. If a user views a specially crafted XBM file, it becomes possible to execute arbitrary code as the user running Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2701 to this issue.
A bug was found in the way Firefox processes certain Unicode sequences. It may be possible to execute arbitrary code as the user running Firefox if the user views a specially crafted Unicode sequence. (CAN-2005-2702)
A bug was found in the way Firefox makes XMLHttp requests. It is possible that a malicious web page could leverage this flaw to exploit other proxy or server flaws from the victim's machine. It is also possible that this flaw could be leveraged to send XMLHttp requests to hosts other than the originator; the default behavior of the browser is to disallow this. (CAN-2005-2703)
A bug was found in the way Firefox implemented its XBL interface. It may be possible for a malicious web page to create an XBL binding in such a way that would allow arbitrary JavaScript execution with chrome permissions. Please note that in Firefox 1.0.6 this issue is not directly exploitable and will need to leverage other unknown exploits. (CAN-2005-2704)
An integer overflow bug was found in Firefox's JavaScript engine. Under favorable conditions, it may be possible for a malicious web page to execute arbitrary code as the user running Firefox. (CAN-2005-2705)
A bug was found in the way Firefox displays about: pages. It is possible for a malicious web page to open an about: page, such as about:mozilla, in such a way that it becomes possible to execute JavaScript with chrome privileges. (CAN-2005-2706)
A bug was found in the way Firefox opens new windows. It is possible for a malicious web site to construct a new window without any user interface components, such as the address bar and the status bar. This window could then be used to mislead the user for malicious purposes. (CAN-2005-2707)
A bug was found in the way Firefox processes URLs passed to it on the command line. If a user passes a malformed URL to Firefox, such as clicking on a link in an instant messaging program, it is possible to execute arbitrary commands as the user running Firefox. (CAN-2005-2968)
Users of Firefox are advised to upgrade to this updated package that contains Firefox version 1.0.7 and is not vulnerable to these issues.
