2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc,
s390, s390x, x86_64

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.
