Executive brief
Microsoft Trace Data Helper is a system utility used to manage diagnostic tracing operations on Windows. An authorized local user can exploit an out-of-bounds read vulnerability to gain elevated privileges, potentially allowing them to run code with system-level permissions. This could be leveraged to compromise system security and gain control of the machine.
Technical details
This vulnerability is an out-of-bounds read in Microsoft Trace Data Helper. An authorized attacker with local access can trigger the out-of-bounds memory read, allowing for privilege escalation to a higher privilege level. The attack vector is local and requires the attacker to already have some form of system access. Successful exploitation enables an attacker to elevate their privileges and gain elevated control over the affected system. A patch from Microsoft is expected to be available through their standard security update process.
