Vulnerability Summary for CVE-2008-4063

Original release date: 09/24/2008
Last revised: 08/19/2013
Source: US-CERT/NIST

Overview

Multiple unspecified vulnerabilities in Mozilla Firefox 3.x before 3.0.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the layout engine and (1) a zero value of the "this" variable in the nsContentList::Item function; (2) interaction of the indic IME extension, a Hindi language selection, and the "g" character; and (3) interaction of the nsFrameList::SortByContentOrder function with a certain insufficient protection of inline frames.

Description

NOTE: Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript such as large images.
