Title: Mozilla products: Multiple vulnerabilities (GLSA 200808-03)
Severity: normal
Exploitable: remote
Date: August 06, 2008
Bug(s): #204337, #218065, #230567, #231975
ID: 200808-03

Synopsis


Multiple vulnerabilities have been reported in Mozilla Firefox,
Thunderbird, SeaMonkey and XULRunner, some of which may allow user-assisted
execution of arbitrary code.


Background


Mozilla Firefox is an open-source web browser and Mozilla Thunderbird
an open-source email client, both from the Mozilla Project. The
SeaMonkey project is a community effort to deliver production-quality
releases of code derived from the application formerly known as the
'Mozilla Application Suite'. XULRunner is a Mozilla runtime package
that can be used to bootstrap XUL+XPCOM applications like Firefox and
Thunderbird.

Description


The following vulnerabilities were reported in all mentioned Mozilla
products:

• 
  TippingPoint's Zero Day Initiative reported that an incorrect integer
  data type is used as a CSS object reference counter, leading to a
  counter overflow and a free() of in-use memory (CVE-2008-2785).
  
• 
  Igor Bukanov, Jesse Ruderman and Gary Kwong reported crashes in the
  JavaScript engine, possibly triggering memory corruption
  (CVE-2008-2799).
  
• 
  Devon Hubbard, Jesse Ruderman, and Martijn Wargers reported crashes in
  the layout engine, possibly triggering memory corruption
  (CVE-2008-2798).
  
• 
  moz_bug_r_a4 reported that XUL documents that include a script from a
  chrome: URI that points to a fastload file would be executed with the
  privileges specified in the file (CVE-2008-2802).
  
• 
  moz_bug_r_a4 reported that the mozIJSSubScriptLoader.LoadScript()
  function only apply XPCNativeWrappers to scripts loaded from standard
  "chrome:" URIs, which could be the case in third-party add-ons
  (CVE-2008-2803).
  
• 
  Astabis reported a crash in the block reflow implementation related to
  large images (CVE-2008-2811).
  
• 
  John G. Myers, Frank Benkstein and Nils Toedtmann reported a weakness
  in the trust model used by Mozilla, that when a user accepts an SSL
  server certificate on the basis of the CN domain name in the DN field,
  the certificate is also regarded as accepted for all domain names in
  subjectAltName:dNSName fields (CVE-2008-2809).
  

The following vulnerabilities were reported in Firefox, SeaMonkey and
XULRunner:

• 
  moz_bug_r_a4 reported that the Same Origin Policy is not properly
  enforced on JavaScript (CVE-2008-2800).
  
• 
  Collin Jackson and Adam Barth reported that JAR signing is not properly
  implemented, allowing injection of JavaScript into documents within a
  JAR archive (CVE-2008-2801).
  
• 
  Opera Software reported an error allowing for arbitrary local file
  upload (CVE-2008-2805).
  
• 
  Daniel Glazman reported that an invalid .properties file for an add-on
  might lead to the usage of uninitialized memory (CVE-2008-2807).
  
• 
  Masahiro Yamada reported that HTML in "file://" URLs in directory
  listings is not properly escaped (CVE-2008-2808).
  
• 
  Geoff reported that the context of Windows Internet shortcut files is
  not correctly identified (CVE-2008-2810).
  
• 
  The crash vulnerability (CVE-2008-1380) that was previously announced
  in GLSA 200805-18 is now also also resolved in Seamonkey binary
  ebuilds.
  

The following vulnerability was reported in Firefox only:

• 
  Billy Rios reported that the Pipe character in a command-line URI is
  identified as a request to open multiple tabs, allowing to open
  "chrome" and "file" URIs (CVE-2008-2933).
  

Impact


A remote attacker could entice a user to view a specially crafted web
page or email that will trigger one of the vulnerabilities, possibly
leading to the execution of arbitrary code or a Denial of Service. It
is also possible for an attacker to trick a user to upload arbitrary
files or to accept an invalid certificate for a spoofed web site, to
read uninitialized memory, to violate Same Origin Policy, or to conduct
Cross-Site Scripting attacks.


Workaround


There is no known workaround at this time.


Resolution


All Mozilla Firefox users should upgrade to the latest version:
