Synopsis

Mozilla Suite and Firefox are vulnerable to multiple issues, including some that might be exploited to execute arbitrary code.

2.  Impact Information

Background

The Mozilla Suite is a popular all-in-one web browser that includes a mail and news reader. Mozilla Firefox is the next-generation browser from the Mozilla project. Gecko is the layout engine used in both products.

Description

The Mozilla Suite and Firefox are both vulnerable to the following issues:

  • Tom Ferris reported a heap overflow in IDN-enabled browsers with malicious Host: headers (CAN-2005-2871).
  • "jackerror" discovered a heap overrun in XBM image processing (CAN-2005-2701).
  • Mats Palmgren reported a potentially exploitable stack corruption using specific Unicode sequences (CAN-2005-2702).
  • Georgi Guninski discovered an integer overflow in the JavaScript engine (CAN-2005-2705)
  • Other issues ranging from DOM object spoofing to request header spoofing were also found and fixed in the latest versions (CAN-2005-2703, CAN-2005-2704, CAN-2005-2706, CAN-2005-2707).

The Gecko engine in itself is also affected by some of these issues and has been updated as well.

Impact

A remote attacker could setup a malicious site and entice a victim to visit it, potentially resulting in arbitrary code execution with the victim's privileges or facilitated spoofing of known websites.

3.  Resolution Information
