SynopsisThe remote Windows host is affected by multiple vulnerabilities.
DescriptionThe remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :
- Multiple elevation of privilege vulnerabilities exist due to improper validation of user-supplied input before loading DLL files. A local attacker can exploit these, via a crafted application, to elevate their privileges and take control of the affected system. (CVE-2016-0014, CVE-2016-0020)
- A remote code execution vulnerability exists in DirectShow due to improper validation of user-supplied input. A remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code in the context of the current user, resulting in taking control of the affected system.
- Multiple remote code execution vulnerabilities exist due to improper validation of user-supplied input before loading DLL files. A local attacker can exploit these, via a specially crafted application, to execute arbitrary code. (CVE-2016-0016, CVE-2016-0018)
- A security bypass vulnerability exists in the Windows Remote Desktop Protocol (RDP) due to a failure to prevent remote logons to accounts that have no passwords set. A remote attacker can exploit this, by using an older version of the RDP client to connect to a Windows 10 host, to generate a list of user accounts.
SolutionMicrosoft 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.
Note that Windows 10 with Citrix XenDesktop installed will not be offered the patch due to an issue with the XenDesktop software that prevents users from logging on when the patch is applied. To apply the patch you must first uninstall XenDesktop or contact Citrix for help with the issue.
