#Security Vulnerability

Improper validation of specified type of input in Windows Authentication Methods allows an authorized attacker to elevate privileges locally.

**According to the CVSS metric, the attack vector is local (AV:L) and the privilege required is none (PR:L). What privileges could an attacker gain with successful exploitation?** A local user could take advantage of this vulnerability and perform elevation of privilege (EOP). By successfully exploiting this vulnerability, the attacker could elevate their privileges to obtain root level access on the virtual machine.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** A user interacting with the file in multiple ways will cause the NTLM hash to be leaked. A few interactions which trigger this leak include: * Opening the parent folder in Explorer * Clicking the file (any mouse button) * Dragging the file * Deleting the file

**How could an attacker exploit this vulnerability?** A remote, unauthenticated attacker could send a crafted event that triggers unsafe object deserialization in a legacy serialization mechanism, resulting in remote code execution.

Improper access control in Microsoft Windows Search Component allows an authorized attacker to deny service locally.

Out-of-bounds read in TCG TPM2.0 allows an authorized attacker to disclose information locally.

**There are multiple update packages available for some of the affected software. Do I need to install all the updates listed in the Security Updates table for the software?** Yes. Customers should apply all updates offered for the software installed on their systems. If multiple updates apply, they can be installed in any order.

Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an unauthorized attacker to perform spoofing over a network.

Use after free in Microsoft Office PowerPoint allows an unauthorized attacker to execute code locally.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.
