RHEL 4 : firefox (RHSA-2006:0610)

medium Nessus Plugin ID 22121

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-2006:0610 advisory.

Mozilla Firefox is an open source Web browser.

The Mozilla Foundation has discontinued support for the Mozilla Firefox 1.0 branch. This update deprecates the Mozilla Firefox 1.0 branch in Red Hat Enterprise Linux 4 in favor of the supported Mozilla Firefox 1.5 branch.

This update also resolves a number of outstanding Firefox security issues:

Several flaws were found in the way Firefox processed certain javascript actions. A malicious web page could execute arbitrary javascript instructions with the permissions of chrome, allowing the page to steal sensitive information or install browser malware. (CVE-2006-2776, CVE-2006-2784, CVE-2006-2785, CVE-2006-2787, CVE-2006-3807, CVE-2006-3809, CVE-2006-3812)

Several denial of service flaws were found in the way Firefox processed certain web content. A malicious web page could crash the browser or possibly execute arbitrary code as the user running Firefox.
(CVE-2006-2779, CVE-2006-2780, CVE-2006-3801, CVE-2006-3677, CVE-2006-3113, CVE-2006-3803, CVE-2006-3805, CVE-2006-3806, CVE-2006-3811)

A cross-site scripting flaw was found in the way Firefox processed Unicode Byte-Order-Mark (BOM) markers in UTF-8 web pages. A malicious web page could execute a script within the browser that a web input sanitizer could miss due to a malformed script tag. (CVE-2006-2783)

Several flaws were found in the way Firefox processed certain javascript actions. A malicious web page could conduct a cross-site scripting attack or steal sensitive information (such as cookies owned by other domains).
(CVE-2006-3802, CVE-2006-3810)

A form file upload flaw was found in the way Firefox handled javascript input object mutation. A malicious web page could upload an arbitrary local file at form submission time without user interaction. (CVE-2006-2782)

A denial of service flaw was found in the way Firefox called the crypto.signText() javascript function. A malicious web page could crash the browser if the victim had a client certificate loaded. (CVE-2006-2778)

Two HTTP response smuggling flaws were found in the way Firefox processed certain invalid HTTP response headers. A malicious web site could return specially crafted HTTP response headers which may bypass HTTP proxy restrictions. (CVE-2006-2786)

A flaw was found in the way Firefox processed Proxy AutoConfig scripts. A malicious Proxy AutoConfig server could execute arbitrary javascript instructions with the permissions of chrome, allowing the page to steal sensitive information or install browser malware. (CVE-2006-3808)

A double free flaw was found in the way the nsIX509::getRawDER method was called. If a victim visited a carefully crafted web page, it was possible to execute arbitrary code as the user running Firefox. (CVE-2006-2788)

Users of Firefox are advised to upgrade to this update, which contains Firefox version 1.5.0.5 that corrects 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-2006:0610.
