Microsoft Word Document Parsing Buffer Overflow Vulnerabilities

-

Description


Two vulnerabilities have been reported in Microsoft Word, which can be exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to boundary errors within the parsing of document files. This can be exploited to cause buffer overflows by tricking a user into opening a specially crafted Word document.

Successful exploitation allows execution of arbitrary code with the privileges of the user running Microsoft Word.


Solution:
Apply patches.
