[DLSLUG-Discuss] FW: US-CERT Technical Cyber Security Alert TA06-208A -- Mozilla Products Contain Multiple Vulnerabilities

Fri Jul 28 19:22:43 EDT 2006

okay, okay... fine... Firefox is flaky at running JavaScript and Java.
  I don't quite understand the Java vulnerabilities since MOST of the work of executing a Java applet work is handled by the java-plugin libraries that Sun or IBM provide with their JVMs. 
  Anyways, not handling JavaScript properly is bad... Very bad... Isn't that kinda necessary for AJAX? 
  so, what I want to know is...
  Are there fixes available for these problems?
  If there are fixes available, on which distributions will the fixes work?
  (Or do I have to download a tarball and compile and install the fixes myself? yuck....)

Technical Cyber Security Alert TA06-208A

Mozilla Products Contain Multiple Vulnerabilities

Original release date: July 27, 2006
Last revised: --
Source: US-CERT

Systems Affected

* Mozilla SeaMonkey
* Mozilla Firefox
* Mozilla Thunderbird

Any products based on Mozilla components, specifically Gecko, may
also
be affected.

Overview

The Mozilla web browser and derived products contain several
vulnerabilities, the most serious of which could allow a remote
attacker to execute arbitrary code on an affected system.

I. Description

Several vulnerabilities have been reported in the Mozilla web browser
and derived products. More detailed information is available in the
individual vulnerability notes, including the following:

VU#476724 - Mozilla products fail to properly handle frame references

Mozilla products fail to properly handle frame or window references.
This may allow a remote attacker to execute arbitrary code on a
vulnerable system.
(CVE-2006-3801)

VU#670060 - Mozilla fails to properly release JavaScript references 

Mozilla products fail to properly release memory. This vulnerability
may allow a remote attacker to execute code on a vulnerable system.
(CVE-2006-3677)

VU#239124 - Mozilla fails to properly handle simultaneous XPCOM
events

Mozilla products are vulnerable to memory corruption via simultaneous
XPCOM events. This may allow a remote attacker to execute arbitrary
code on a vulnerable system.
(CVE-2006-3113)

VU#265964 - Mozilla products contain a race condition 

Mozilla products contain a race condition. This vulnerability may
allow a remote attacker to execute code on a vulnerable system.
(CVE-2006-3803)

VU#897540 - Mozilla products VCard attachment buffer overflow 

Mozilla products fail to properly handle malformed VCard attachments,
allowing a buffer overflow to occur. This vulnerability may allow a
remote attacker to execute arbitrary code on a vulnerable system.
(CVE-2006-3804)

VU#876420 - Mozilla fails to properly handle garbage collection 

The Mozilla JavaScript engine fails to properly perform garbage
collection, which may allow a remote attacker to execute arbitrary
code on a vulnerable system.
(CVE-2006-3805)

VU#655892 - Mozilla JavaScript engine contains multiple integer
overflows 

The Mozilla JavaScript engine contains multiple integer overflows.
This vulnerability may allow a remote attacker to execute arbitrary
code on a vulnerable system.
(CVE-2006-3806)

VU#687396 - Mozilla products fail to properly validate JavaScript
constructors 

Mozilla products fail to properly validate references returned by
JavaScript constructors. This vulnerability may allow a remote
attacker to execute arbitrary code on a vulnerable system.
(CVE-2006-3807)

VU#527676 - Mozilla contains multiple memory corruption
vulnerabilities 

Mozilla products contain multiple vulnerabilities that can cause
memory corruption. This may allow a remote attacker to execute
arbitrary code on a vulnerable system.
(CVE-2006-3811)

II. Impact

A remote, unauthenticated attacker could execute arbitrary code on a
vulnerable system. An attacker may also be able to cause the
vulnerable application to crash.

III. Solution

Upgrade

Upgrade to Mozilla Firefox 1.5.0.5, Mozilla Thunderbird 1.5.0.5, or
SeaMonkey 1.0.3.

Disable JavaScript and Java

These vulnerabilities can be mitigated by disabling JavaScript and
Java in all affected products. Instructions for disabling Java in
Firefox can be found in the "Securing Your Web Browser" document.
