Description


Multiple vulnerabilities have been reported in Microsoft Internet Explorer, which can be exploited by malicious people to disclose sensitive information and compromise a user's system.

1) An error when handling the encoding for Shift_JIS auto-selection can be exploited to gain access to information in another domain or Internet Explorer zone.

2) A use-after-free error within the "SetCapture()" method can be exploited to dereference an invalid pointer.

3) A use-after-free error within the "COmWindowProxy" class when handling the window.open event can be exploited to dereference an invalid pointer.

4) A use-after-free error within the "document.adoptNode()" method when handling CMarkup and CDATA objects can be exploited to dereference an invalid pointer.

5) A use-after-free error related to vtable can be exploited to access an already freed object.

6) A use-after-free error related to LsGetTrailInfo can be exploited to access an already freed object.

7) A use-after-free error within the "CDispNode" class when handling SVG objects can be exploited to dereference already freed memory.

8) A use-after-free error within the "pasteHTML()" method when handling TextRange objects can be exploited to dereference an invalid pointer.

9) A use-after-free error when handling the "CParaElement" node of the "SLayoutRun" class can be exploited to reference an already freed object.

10) A use-after-free error related to InsertElement can be exploited to access an already freed object.

11) A use-after-free error related to CPasteCommand can be exploited to access an already freed object.

12) A use-after-free error within the "CObjectElement" class when handling CSS cursor properties can be exploited to dereference an invalid pointer.

13) A use-after-free when handling a "CSelectionManager" object via the "onbeforedeactivate" event can be exploited to dereference an invalid pointer.

Successful exploitation of the vulnerabilities #2 through #13 allows the execution of arbitrary code.
