Mozilla Firefox before 2.0.0.19 and 3.x before 3.0.5, SeaMonkey, and Thunderbird allow remote attackers to cause a denial of service (memory consumption and application crash) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.

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)
 - XSS vulnerabilities in SessionStore may allow for violating the browser's same-origin policy and performing an XSS attack or running arbitrary JavaScript with chrome privileges. (MFSA 2008-69)
 - A denial of service issue when the application handles a maliciously crafted webpage containing a 'HTMLSelectElement' object with a large length attribute.

The installed version of Firefox 3.0 is earlier than 3.0.5.  Such versions are potentially 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)

  - The 'persist' attribute in XUL elements can be used to     store cookie-like information on a user's computer.
    (MFSA 2008-63)

  - 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 that redirects to an off-domain target     resource containing data which 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)

  - XSS vulnerabilities in SessionStore may allow for     violating the browser's same-origin policy and     performing an XSS attack or running arbitrary     JavaScript with chrome privileges. (MFSA 2008-69)

  - Creating a Select object with a very large length can     result in memory exhaustion, causing a denial of     service. (CVE-2009-2535)

  - Cross-site scripting and JavaScript privilege escalation     are possible. (MFSA 2008-68)

  - Cross-site scripting vulnerabilities in SessionStore may     allow for violating the browser's same-origin policy and     performing an XSS attack or running arbitrary     JavaScript with chrome privileges. (MFSA 2008-69)

Note that Mozilla is not planning further security / stability updates for Firefox 2.
