medium Nessus Plugin ID 334602

Language:

Synopsis

The Microsoft PowerPoint Products are affected by an information disclosure vulnerability.

Description

The Microsoft PowerPoint Products are missing a security update. They are, therefore, affected by an information disclosure vulnerability. Incomplete cleanup in Microsoft Office PowerPoint allows an unauthorized attacker to disclose information locally.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Microsoft has released KB5002899 to address this issue.
