Microsoft Windows SMB Packet Processing Vulnerabilities

-

Description


Two vulnerabilities have been reported in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

1) An integer underflow error when processing a Browser Election request can be exploited to cause a buffer overflow via an overly long Server Name string sent in a specially crafted packet.

Successful exploitation of this vulnerability may allow execution of arbitrary code, but requires the target system to be a Master Browser.

2) A validation error when processing Server Message Block (SMB) responses can be exploited by sending a specially crafted response to a client-initiated SMB request.

Successful exploitation of this vulnerability allows execution of arbitrary code, but requires tricking a user into connecting to a malicious SMB server (e.g. via a link hosted on a web page).


Solution:
Apply patches.
