Gentoo Linux Security Advisory

Title: Mozilla SeaMonkey: Multiple vulnerabilities (GLSA 200608-02)
Severity: normal
Exploitable: remote
Date: August 03, 2006
Bug(s): #141842
ID: 200608-02


The Mozilla Foundation has reported numerous security vulnerabilities
related to Mozilla SeaMonkey.


The Mozilla SeaMonkey project is a community effort to deliver
production-quality releases of code derived from the application
formerly known as "Mozilla Application Suite".

Affected Packages

Package: www-client/seamonkey
Vulnerable: < 1.0.3
Unaffected: >= 1.0.3
Architectures: All supported architectures


The following vulnerabilities have been reported:
  • Benjamin Smedberg discovered that chrome URL's could be made to
    reference remote files.
  • Developers in the Mozilla community
    looked for and fixed several crash bugs to improve the stability of
    Mozilla clients, which could lead to the execution of arbitrary code by
    a remote attacker.
  • "shutdown" reports that cross-site
    scripting (XSS) attacks could be performed using the construct
    XPCNativeWrapper(window).Function(...), which created a function that
    appeared to belong to the window in question even after it had been
    navigated to the target site.
  • "shutdown" reports that scripts
    granting the UniversalBrowserRead privilege can leverage that into the
    equivalent of the far more powerful UniversalXPConnect since they are
    allowed to "read" into a privileged context.
  • "moz_bug_r_a4"
    reports that A malicious Proxy AutoConfig (PAC) server could serve a
    PAC script that can execute code with elevated privileges by setting
    the required FindProxyForURL function to the eval method on a
    privileged object that leaked into the PAC sandbox.
  • "moz_bug_r_a4" discovered that Named JavaScript functions have a
    parent object created using the standard Object() constructor
    (ECMA-specified behavior) and that this constructor can be redefined by
    script (also ECMA-specified behavior).
  • Igor Bukanov and
    shutdown found additional places where an untimely garbage collection
    could delete a temporary object that was in active use.
  • Georgi
    Guninski found potential integer overflow issues with long strings in
    the toSource() methods of the Object, Array and String objects as well
    as string function arguments.
  • H. D. Moore reported a testcase
    that was able to trigger a race condition where JavaScript garbage
    collection deleted a temporary variable still being used in the
    creation of a new Function object.
  • A malicious page can hijack
    native DOM methods on a document object in another domain, which will
    run the attacker's script when called by the victim page.
  • Secunia Research has discovered a vulnerability which is caused due
    to an memory corruption error within the handling of simultaneously
    happening XPCOM events. This leads to use of a deleted timer
  • An anonymous researcher for TippingPoint and the Zero
    Day Initiative showed that when used in a web page Java would reference
    properties of the window.navigator object as it started up.
  • Thilo Girmann discovered that in certain circumstances a JavaScript
    reference to a frame or window was not properly cleared when the
    referenced content went away.


A user can be enticed to open specially crafted URLs, visit webpages
containing malicious JavaScript or execute a specially crafted script.
These events could lead to the execution of arbitrary code, or the
installation of malware on the user's computer.


There is no known workaround at this time.


All Thunderbird users should upgrade to the latest version:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/seamonkey-1.0.3"
