Oracle Linux 4 : firefox (ELSA-2006-0733 / ELSA-2006-0675 / ELSA-2006-0610)

Critical Nessus Plugin ID 67422

Synopsis

The remote Oracle Linux host is missing a security update.

Description

Updated firefox packages that fix several security bugs are now available for Red Hat Enterprise Linux 4.

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

Mozilla Firefox is an open source Web browser.

Users of Firefox are advised to upgrade to these erratum packages, which contain Firefox version 1.5.0.8 that corrects these issues.


From Red Hat Security Advisory 2006:0733 :

Several flaws were found in the way Firefox processes certain malformed Javascript code. A malicious web page could cause the execution of Javascript code in such a way that could cause Firefox to crash or execute arbitrary code as the user running Firefox. (CVE-2006-5463, CVE-2006-5747, CVE-2006-5748)

Several flaws were found in the way Firefox renders web pages. A malicious web page could cause the browser to crash or possibly execute arbitrary code as the user running Firefox. (CVE-2006-5464)

A flaw was found in the way Firefox verifies RSA signatures. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. Firefox as shipped trusts several root Certificate Authorities that use exponent 3. An attacker could have created a carefully crafted SSL certificate which be incorrectly trusted when their site was visited by a victim. This flaw was previously thought to be fixed in Firefox 1.5.0.7, however Ulrich Kuehn discovered the fix was incomplete (CVE-2006-5462)


From Red Hat Security Advisory 2006:0675 :

Two flaws were found in the way Firefox processed certain regular expressions. A malicious web page could crash the browser or possibly execute arbitrary code as the user running Firefox. (CVE-2006-4565, CVE-2006-4566)

A number of flaws were found in Firefox. A malicious web page could crash the browser or possibly execute arbitrary code as the user running Firefox. (CVE-2006-4571)

A flaw was found in the handling of Javascript timed events. A malicious web page could crash the browser or possibly execute arbitrary code as the user running Firefox. (CVE-2006-4253)

Daniel Bleichenbacher recently described an implementation error in RSA signature verification. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. Firefox as shipped trusts several root Certificate Authorities that use exponent 3. An attacker could have created a carefully crafted SSL certificate which be incorrectly trusted when their site was visited by a victim. (CVE-2006-4340)

A flaw was found in the Firefox auto-update verification system. An attacker who has the ability to spoof a victim's DNS could get Firefox to download and install malicious code. In order to exploit this issue an attacker would also need to get a victim to previously accept an unverifiable certificate. (CVE-2006-4567)

Firefox did not properly prevent a frame in one domain from injecting content into a sub-frame that belongs to another domain, which facilitates website spoofing and other attacks (CVE-2006-4568)

Firefox did not load manually opened, blocked popups in the right domain context, which could lead to cross-site scripting attacks. In order to exploit this issue an attacker would need to find a site which would frame their malicious page and convince the user to manually open a blocked popup. (CVE-2006-4569)


From Red Hat Security Advisory 2006:0610 :

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)

Solution

Update the affected firefox package.
