MS15-111: Security Update for Windows Kernel to Address Elevation of Privilege (3096447)

High Nessus Plugin ID 86373


The remote Windows host is affected by multiple vulnerabilities.


The remote Windows host is affected by the following vulnerabilities :

- Multiple elevation of privilege vulnerabilities exist in the Windows kernel due to improper handling of objects in memory. A local attacker can exploit these vulnerabilities, via a specially crafted application, to execute arbitrary code in kernel mode. (CVE-2015-2549, CVE-2015-2550, CVE-2015-2554)

- A security feature bypass vulnerability exists due to a failure to properly enforce the Windows Trusted Boot policy. A local attacker can exploit this, via a specially crafted Boot Configuration Data (BCD) setting, to disable code integrity checks, resulting in the execution of test-signed executables and drivers.
Additionally, a local attacker can exploit this vulnerability to bypass Trusted Boot integrity validation for BitLocker and Device Encryption security features. (CVE-2015-2552)

- An elevation of privilege vulnerability exists due to improper validation of junctions in certain scenarios in which mount points are being created. An unauthenticated, remote attacker can exploit this in conjunction with another vulnerability to execute arbitrary code in the context of the current user.


Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 8, RT, 2012, 8.1, RT 8.1, 2012 R2, and 10.
