Title: PowerPoint File Parsing Vulnerability
Date: January 22, 2001
Software: PowerPoint 2000
Impact: Execution of Arbitrary Code
Bulletin: MS01-002

Issue:

A parsing routine that is executed when PowerPoint 2000 opens files
contains an unchecked buffer. If an attacker inserted specially
chosen data into a PowerPoint file and could entice another user into
opening the file on his machine, the data would overrun the buffer,
causing either of two effects. In the less serious case, overrunning
the data would cause PowerPoint to fail, but wouldn't have any other
effect. In the more serious case, overrunning the buffer could allow
the attacker to cause code of her choice to run on the user's
machine. The code could take any action that the user himself could
take on the machine. Typically, this would enable the attacker's code
to add, change or delete data, communicate with a remote server, or
take other actions.

Mitigating Factors:

  • The user would need to be enticed into opening a malformed
    PowerPoint file
