ZDI-06-010: Mozilla Firefox CSS Letter-Spacing Heap Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-06-010.html
April 13, 2006

-- CVE ID:
CVE-2006-1730

-- Affected Vendor:
Mozilla

-- Affected Products:
Mozilla 1.7.x and below
Firefox 1.5.x and below

TippingPoint IPS customers have been protected against this
vulnerability since January 31, 2006 by Digital Vaccine protection
filter ID 4097. For further product information on the TippingPoint IPS:

-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of the Mozilla/Firefox web browser. User
interaction is required to exploit this vulnerability in that the
target must visit a malicious page.

The specific flaw is due to incorrect handling of the CSS
"letter-spacing" element. By specifying a large number, an attacker can
overflow an integer used during memory allocation. The under-allocated
buffer is later used to store user-supplied data leading to an
exploitable heap overflow.

-- Vendor Response:
Mozilla has issued an update to correct this vulnerability. Details are
available at:
http://www.mozilla.org/security/announce/2006/mfsa2006-22.html
