Successful exploitation of this vulnerability may allow execution of arbitrary code. 3) An error in the implementation of "navigator.plugins" can be exploited to trigger the use of an invalid pointer and execute arbitrary code. 4) An error when transforming text runs can be exploited to cause a heap-based buffer overflow via a specially crafted page containing bidirectional text run. Successful exploitation of this vulnerability may allow execution of arbitrary code. 5) An use-after-free error in the handling of XUL tree selections can be exploited to corrupt memory and execute arbitrary code. This is related to vulnerability #7 in: SA39925 6) An error in the handling of XUL tree objects can be exploited to trigger the removal of the tree from the DOM and cause certain sections of deleted memory to be accessed. Successful exploitation allows execution of arbitrary code in products based on Gecko version 1.9.1 (e.g. Firefox 3.5). 7) An error in the handling of "nsTreeContentView" can be exploited to remove a node prior to accessing it. Successful exploitation of this vulnerability may allow execution of arbitrary code. 8) An error when normalising a document can be exploited to trigger the use of a deleted object. Successful exploitation of this vulnerability may allow execution of arbitrary code. 9) An error in the handling of fonts applied to a document can be exploited to corrupt memory and potentially execute arbitrary code on a Mac system. 10) The wrapper class "XPCSafeJSObjectWrapper" (SJOW) creates scope chains ending in outer objects. This may be exploited to execute arbitrary javascript code with chrome privileges if users of SJOWs expect the scope chain to end on an inner object. 11) A logic error in the wrapper class "XPCSafeJSObjectWrapper" (SJOW) allows to run a function within the context of another site. This can be exploited to bypass the same-origin policy and conduct cross-site scripting attacks. 12) An error in the handling of the type attribute of an tag can be used to override the charset of a framed HTML document, even when the document is included across origins. This can be exploited inject and execute UTF-7 encoded javascript code into a site, potentially bypassing cross-site scripting filters. 13) An error when copy-and-pasting or drag-and-dropping HTML code onto a document with designMode enabled can be exploited to execute arbitrary javascript code in the context of the site where the code is dropped. 14) The "statusText" property of an XMLHttpRequest object is readable by the requestor even when the request is made across origins. This can be exploited to gain information about servers within internal networks. SOLUTION: Update to version 3.6.9 or 3.5.12.
