http://www.zerodayinitiative.com/advisories/ZDI-10-050
April 2, 2010
-- CVE ID:
CVE-2010-0175
-- Affected Vendors:
Mozilla Firefox
-- Affected Products:
Mozilla Firefox 3.5.x
-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
software utilizing a vulnerable version of Mozilla's Firefox. User
interaction is required in that the victim must visit a malicious
website or be coerced into opening a malicious document.
The specific flaw exists within how the application handles particular
events for an nsTreeSelection element. Upon execution of a "select"
event the application will access an element without checking to see if
it's been previously freed or not. Successful exploitation can lead to
code execution under the context of the application.
-- Vendor Response:
Mozilla Firefox has issued an update to correct this vulnerability. More
