Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to improper handling of malformed TrueType font files by the kernel-mode driver (win32k.sys). A remote attacker can create a specially crafted TrueType font file, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
