Firefox 8.x Multiple Vulnerabilities (Mac OS X)

High Nessus Plugin ID 57359


The remote Mac OS X host contains a web browser that is potentially affected by several vulnerabilities.


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)

- Various memory safety errors exist that can lead to memory corruption and possible code execution.

- 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)

- 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.

- 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)


Upgrade to Firefox 9.0 or later.
