SeaMonkey 2.x < 2.9.0 Multiple Vulnerabilities

High

Synopsis

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

Description

Versions of SeaMonkey 2.x earlier than 2.9.0 are potentially affected by the following security issues :

- An error exists with the handling of JavaScript errors that can lead to information disclosure. (CVE-2011-1187)

- An off-by-one error exists in the 'OpenType Sanitizer' that can lead to out-bounds-reads and possible code execution. (CVE-2011-3062)

- Memory safety issues exist which 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' which can lead to possible code execution. (CVE-2012-0470)

- A multi-octet encoding issue exists which 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' which can cause memory corruption leading to crashes and potentially code execution. (CVE-2012-0472)

- An error exists in 'WebGLBuffer' that can lead to the reading of illegal video memory. (CVE-2012-0473)

- An unspecified error can allow URL bar spoofing. (CVE-2012-0474)

- IPv6 addresses and cross-site 'XHR' or 'WebSocket' connections on non-standard ports can 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 which could lead to cross-site scripting attacks. (CVE-2012-0477)

- An error exists related to 'WebGL' and 'texImage2D' that can 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 SeaMonkey 2.9.0 or later.
