Several flaws were discovered in the browser engine. These problems could allow an attacker to crash the browser and possibly execute arbitrary code with user privileges. (CVE-2008-5500)

Boris Zbarsky discovered that the same-origin check in Firefox could be bypassed by utilizing XBL-bindings. An attacker could exploit this to read data from other domains. (CVE-2008-5503)

Marius Schilder discovered that Firefox did not properly handle redirects to an outside domain when an XMLHttpRequest was made to a same-origin resource. It's possible that sensitive information could be revealed in the XMLHttpRequest response. (CVE-2008-5506)

Chris Evans discovered that Firefox did not properly protect a user's data when accessing a same-domain JavaScript URL that is redirected to an unparsable JavaScript off-site resource. If a user were tricked into opening a malicious website, an attacker may be able to steal a limited amount of private data. (CVE-2008-5507)

Several flaws were discovered in the JavaScript engine. If a user were tricked into opening a malicious website, an attacker could exploit this to execute arbitrary JavaScript code within the context of another website or with chrome privileges. (CVE-2008-5511, CVE-2008-5512).

From Red Hat Security Advisory 2008:1037 :

Updated SeaMonkey packages that fix security issues are now available for Red Hat Enterprise Linux 2.1, Red Hat Enterprise Linux 3, and Red Hat Enterprise Linux 4.

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

SeaMonkey is an open source Web browser, email and newsgroup client, IRC chat client, and HTML editor.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code as the user running SeaMonkey.
(CVE-2008-5500, CVE-2008-5501, CVE-2008-5502, CVE-2008-5504, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513)

Several flaws were found in the way malformed content was processed. A website containing specially crafted content could potentially trick a SeaMonkey user into surrendering sensitive information.
(CVE-2008-5503, CVE-2008-5506, CVE-2008-5507)

A flaw was found in the way malformed URLs were processed by SeaMonkey. This flaw could prevent various URL sanitization mechanisms from properly parsing a malicious URL. (CVE-2008-5508)

Note: after the errata packages are installed, SeaMonkey must be restarted for the update to take effect.

All SeaMonkey users should upgrade to these updated packages, which contain backported patches to resolve these issues.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

Versions of Firefox 3.x prior to 3.0.5 are affected by the following security issues : 

 - There are several stability bugs in the browser engine that may lead to crashes with evidence of memory corruption. (MFSA 2008-60)
 - XBL bindings can be used to read data from other domains. (MFSA 2008-61)
 - The feed preview still allows for JavaScript privilege escalation. (MFSA 2008-62)
 - Sensitive data may be disclosed in an XHR response when an XMLHttpRequest is made to a same-origin resource, which 302 redirects to a resource in a different domain. (MFSA 2008-64)
 - A website may be able to access a limited amount of data from a different domain by loading a same-domain JavaScript URL which redirects to an off-domain target resource containing data that is not parsable as JavaScript. (MFSA 2008-65)
 - Errors arise when parsing URLs with leading whitespace and control characters. (MFSA 2008-66)
 - An escaped null byte is ignored by the CSS parser and treated as if it was not present in the CSS input string. (MFSA 2008-67)
 - XSS and JavaScript privilege escalation are possible. (MFSA 2008-68)
