Fedora 7 : firefox- (2007-0001)

High Nessus Plugin ID 27648


The remote Fedora host is missing a security update.


Updated firefox packages that fix several security bugs are now available for Fedora Core 7.

This update has been rated as having critical security impact by the Fedora Security Response Team.

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed JavaScript code. A web page containing malicious JavaScript code could cause Firefox to crash or potentially execute arbitrary code as the user running Firefox. (CVE-2007-2867, CVE-2007-2868)

A flaw was found in the way Firefox handled certain FTP PASV commands.
A malicious FTP server could use this flaw to perform a rudimentary port-scan of machines behind a user's firewall. (CVE-2007-1562)

Several denial of service flaws were found in the way Firefox handled certain form and cookie data. A malicious website that is able to set arbitrary form and cookie data could prevent Firefox from functioning properly. (CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way Firefox handled the addEventListener JavaScript method. A malicious website could use this method to access or modify sensitive data from another website. (CVE-2007-2870)

A flaw was found in the way Firefox displayed certain web content. A malicious web page could generate content that would overlay user interface elements such as the hostname and security indicators, tricking users into thinking they are visiting a different site.

Users of Firefox are advised to upgrade to these erratum packages, which contain Firefox version that corrects these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected firefox, firefox-debuginfo and / or firefox-devel packages.
