Microsoft Patch Tuesday November 2016 brings 14 Security bulletins addressing 75 Vulnerabilities. Six of which are rated as Critical, eight are rated as Important. A vulnerability management solution can fix these vulnerabilities.
The Six Critical bulletins are as follows:
- MS16-129 for Microsoft’s Edge browser covers 17 CVE’s
- MS16-130 for Microsoft Windows covers 3 CVE’s
- MS16-131 for Microsoft Video Control covers 1 CVE’s
- MS16-132 for Microsoft Graphics Component covers 4 CVE’s
- MS16-141 for Adobe Flash Player covers 9 CVE’s
- MS16-142 for Internet Explorer covers 7 CVE’s
Critical vulnerabilities allow remote attackers to perform Remote Code Execution. However, a patch management solution can mitigate these. The other bulletins which are marked as important allow Remote code execution, Elevation of Privilege and Security Feature Bypass.
One zero-day vulnerability is addressed by November 2016 Patch Tuesday update.
MS16-135(CVE-2016-7255) addresses a zero-day flaw (Windows zero-day flaw) which allows attackers to do local privilege escalation. Also, It can be used as a security sandbox escape. However, Attackers can run arbitrary code in kernel mode and log on to an affected system and runs a specially crafted application that could exploit the vulnerabilities and take control of an affected system. It can be triggered via the win32k.sys system call NtSetWindowLongPtr() for the index GWLP_ID on a window handle with GWL_STYLE set to WS_CHILD. Chrome’s sandbox blocks win32k.sys system calls using the Win32k lockdown mitigation on Windows 10, which prevents exploitation of this sandbox escape vulnerability(https://security.googleblog.com/2016/10/disclosing-vulnerabilities-to-protect.html).
