In short
A flaw in Windows' log file system driver allows an attacker with regular user access to gain administrator-level privileges on the system. This is dangerous because it lets attackers take complete control of the computer.
Technical detail
A buffer overflow (CWE-787) in the Common Log File System (CLFS) driver allows local privilege escalation through improper input validation. An authenticated local user can exploit this vulnerability to execute arbitrary code in kernel context and obtain SYSTEM privileges.
