Mozilla Firefox < 12.0 Multiple Vulnerabilities

High

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Firefox less than 11 are potentially affected by the following security issues :

- An error exists with handling JavaScript errors that could lead to information disclosure. (CVE-2011-1187) - An off-by-one error exists in the 'OpenType Sanitizer' that could lead to out-bounds-reads and possible code execution. (CVE-2011-3062) - Memory safety issues exist that could lead to arbitrary code execution. (CVE-2012-0467, CVE-2012-0468) - A use-after-free error exists related to 'IDBKeyRange' of 'indexedDB'. (CVE-2012-0469) - Heap-corruption errors exist related to 'gfxImageSurface' that could lead to possible code execution. (CVE-2012-0470) - A multi-octet encoding issue exists that could allow cross-site scripting attacks as certain octets in multibyte character sets can destroy following octets.(CVE-2012-0471) - An error exists related to font rendering with 'cairo-dwrite' that could cause memory corruption leading to crashes and potentially code execution. (CVE-2012-0472) - An error exists in 'WebGLBuffer' that could lead to the reading of illegal video memory. (CVE-2012-0473) - An unspecified error could allow URL bar spoofing. (CVE-2012-0474) - IPv6 addresses and cross-site 'XHR' or 'WebSocket' connections on non-standard ports could allow this application to send ambiguous origin headers. (CVE-2012-0475) - A decoding issue exists related to 'ISO-2022-KR' and 'ISO-2022-CN' character sets that could lead to cross-site scripting attacks. (CVE-2012-0477) - An error exists related to 'WebGL' and 'texImage2D' that could allow application crashes and possibly code execution when 'JSVAL_TO_OBJECT' is used on ordinary objects. (CVE-2012-0478) - Address bar spoofing is possible when 'Atom XML' or 'RSS' data is loaded over HTTPS leading to phishing attacks. (CVE-2012-0479)

Solution

Upgrade to Firefox 12.0 or later.
