MS11-034: Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (2506223)

Synopsis :

The remote Windows kernel is affected by multiple vulnerabilities.

Description :

The remote host is running a version of the Windows kernel that is
affected by the following types of vulnerabilities :

- Several use-after-free vulnerabilities exist due to the
way that Windows kernel-mode drivers manage kernel-mode
driver objects. (CVE-2011-0662, CVE-2011-0665,
CVE-2011-0666, CVE-2011-0667, CVE-2011-0670,
CVE-2011-0671, CVE-2011-0672, CVE-2011-0674,
CVE-2011-0675, CVE-2011-1234, CVE-2011-1235,
CVE-2011-1236, CVE-2011-1237, CVE-2011-1238,
CVE-2011-1239, CVE-2011-1240, CVE-2011-1241,
CVE-2011-1242)

- Several null pointer de-reference vulnerabilities exist
due to the way that Windows kernel-mode drivers manage
pointers to kernel-mode driver objects. (CVE-2011-0673,
CVE-2011-0676, CVE-2011-0677, CVE-2011-1225,
CVE-2011-1226, CVE-2011-1227, CVE-2011-1228,
CVE-2011-1229, CVE-2011-1230, CVE-2011-1231,
CVE-2011-1232, CVE-2011-1233)

An attacker with local access to the affected system can exploit these
issues to execute arbitrary code in kernel mode and take complete
control of the affected system.
