The installed version of SeaMonkey is earlier than 2.6.0.  Such versions are potentially affected by the following security issues :

  - An out-of-bounds memory access error exists in the     'SVG' implementation and can be triggered when 'SVG'     elements are removed during a 'DOMAttrModified' event     handler. (CVE-2011-3658)

  - Various memory safety errors exist that can lead to     memory corruption and possible code execution.
    (CVE-2011-3660)

  - An error exists in the 'YARR' regular expression     library that can cause application crashes when     handling certain JavaScript statements. (CVE-2011-3661)

  - It is possible to detect keystrokes using 'SVG'     animation 'accesskey' events even when JavaScript is     disabled. (CVE-2011-3663)

  - It is possible to crash the application when 'OGG'     'video' elements are scaled to extreme sizes.
    (CVE-2011-3665)

  - A use-after-free error exists related to the function     'nsHTMLSelectElement' that can allow arbitrary code     execution during operations such as removal of a     parent node of an element. (CVE-2011-3671)

The installed version of Firefox is earlier than 9.0 and thus, is potentially affected by the following security issues :

  - An out-of-bounds memory access error exists in the     'SVG' implementation and can be triggered when 'SVG'     elements are removed during a 'DOMAttrModified' event     handler. (CVE-2011-3658)

The installed version of Firefox 8.x is potentially affected by the following security issues :

  - An out-of-bounds memory access error exists in the     'SVG' implementation and can be triggered when 'SVG'     elements are removed during a 'DOMAttrModified' event     handler. (CVE-2011-3658)

  - It is possible to detect keystrokes using 'SVG'     animation 'accesskey' events even when JavaScript is     disabled. (CVE-2011-3663)

  - An error exists related to plugins that can allow a NULL     pointer to be dereferenced when a plugin deletes its     containing DOM frame during a call from that frame. It     may be possible for a non-NULL pointer to be     dereferenced thereby opening up the potential for     further exploitation. (CVE-2011-3664)

  - It is possible to crash the application when 'OGG'        'video' elements are scaled to extreme sizes.
