Disclosing vulnerabilities to protect users
31 tháng 10, 2016
Posted by Neel Mehta and Billy Leonard, Threat Analysis Group
On Friday, October 21st, we reported 0-day vulnerabilities — previously publicly-unknown vulnerabilities — to Adobe and Microsoft. Adobe updated Flash
on October 26th
to address CVE-2016-7855; this update is available via Adobe's updater and Chrome auto-update.
After 7 days, per our
published policy for actively exploited critical vulnerabilities
, we are today disclosing the existence of a remaining critical vulnerability in Windows for which no advisory or fix has yet been released. This vulnerability is particularly serious because we know it is being actively exploited.
The Windows vulnerability is a local privilege escalation in the Windows kernel that can be used as a security sandbox escape. 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.
We encourage users to verify that auto-updaters have already updated Flash — and to manually update if not — and to apply Windows patches from Microsoft when they become available for the Windows vulnerability.
