Description:   Multiple vulnerabilities were reported in Microsoft Internet Explorer. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can delete files on the target system. A remote user can gain elevated privileges. A remote user can obtain potentially sensitive information on the target system.

A remote user can create specially crafted content that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target user's system [CVE-2015-2485, CVE-2015-2486, CVE-2015-2487, CVE-2015-2490, CVE-2015-2491, CVE-2015-2492, CVE-2015-2494, CVE-2015-2498, CVE-2015-2499, CVE-2015-2500, CVE-2015-2501, CVE-2015-2541, CVE-2015-2542].

A remote user that can exploit a separate script execution vulnerability can trigger a flaw in the validation of permissions to cause the script to be run with elevated privileges on the target system [CVE-2015-2489]. Internet Explorer 11 is affected.

A remote user can exploit a memory object handling flaw to view potentially sensitive application memory contents [CVE-2015-2483]. Internet Explorer 10 and 11 are affected.

A remote user that can exploit a separate vulnerability can exploit a file operation permissions flaw to delete arbitrary files on the target system [CVE-2015-2484]. Internet Explorer 10 and 11 are affected.

A remote user can create specially crafted content that, when loaded by the target user, will trigger a memory object handling flaw in the VBScript and JScript engines to execute arbitrary code [CVE-2015-2493]. This can also be exploited via an application or Microsoft Office document that contains an embedded ActiveX control marked "safe for initialization". Internet Explorer 8 is affected.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user that can exploit a separate script execution flaw can gain elevated privileges on the target system.

A remote user can obtain potentially sensitive information on the target system.

A remote user that can exploit a separate flaw can delete arbitrary files on the target system.

Solution:   The vendor has issued a fix.
