3. Problem description:

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.
