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 authenticated user can gain elevated privileges on the target system. A remote user can bypass security protections on the target system.

A remote user can create specially crafted HTML that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2015-1658, CVE-2015-1684, CVE-2015-1685, CVE-2015-1686, CVE-2015-1688, CVE-2015-1689, CVE-2015-1691, CVE-2015-1692, CVE-2015-1694, CVE-2015-1703, CVE-2015-1704, CVE-2015-1705, CVE-2015-1706, CVE-2015-1708, CVE-2015-1709, CVE-2015-1710, CVE-2015-1711, CVE-2015-1712, CVE-2015-1713, CVE-2015-1714, CVE-2015-1717, CVE-2015-1718]. The code will run with the privileges of the target user.

A remote authenticated user that can exploit a separate vulnerability can gain elevated privileges on the target system [CVE-2015-1688, CVE-2015-1703, CVE-2015-1704, CVE-2015-1713].

A remote user can bypass address space layout randomization (ASLR) protections [CVE-2015-1684, CVE-2015-1685, CVE-2015-1686].
