Microsoft Security Advisory 4025685: Guidance for older platforms (XP / 2003) (EXPLODINGCAN)

Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host is missing a security update. It is,
therefore, affected by one or more of the following vulnerabilities :

- A remote code execution vulnerability exists in how the
Remote Desktop Protocol (RDP) handles requests if the
RDP server has Smart Card authentication enabled. An
authenticated, remote attacker can exploit this, via a
specially crafted application, to execute arbitrary code
with full user privileges. (CVE-2017-0176)

- A remote code execution vulnerability exists in
Microsoft Internet Explorer due to improper handling of
objects in memory. An unauthenticated, remote attacker
can exploit this, by convincing a user to visit a
specially crafted website, to execute arbitrary code in
the context of the current user. (CVE-2017-0222)

- An information disclosure vulnerability exists in the
Microsoft Server Message Block 1.0 (SMBv1) server when
handling certain requests. An unauthenticated, remote
attacker can exploit this, via a specially crafted
packet, to disclose sensitive information.
(CVE-2017-0267)

- A buffer overflow condition exists in the IIS WebDAV
service due to improper handling of the 'If' header in a
PROPFIND request. An unauthenticated, remote attacker
can exploit this, via a specially crafted request, to
cause a denial of service condition or the execution of
arbitrary code. This vulnerability, also known as
EXPLODINGCAN, is one of multiple Equation Group
vulnerabilities and exploits disclosed on 2017/04/14 by
a group known as the Shadow Brokers. (CVE-2017-7269)

- A remote code execution vulnerability exists in how the
Remote Desktop Protocol (RDP) handles requests if the
RDP server has Routing and Remote Access enabled. An
authenticated, remote attacker can exploit this, via a
specially crafted application, to execute arbitrary code
with full user privileges. (CVE-2017-8461)

- A remote code execution vulnerability exists in Windows
OLE, specifically in olecnv32.dll, due to improper
validation of user-supplied input. An unauthenticated,
remote attacker can exploit this, by convincing a user
to visit a specially crafted website or to open a
specially crafted file or email, to execute arbitrary
code in the context of the current user. (CVE-2017-8487)

- A remote code execution vulnerability exists in the
Windows Search functionality due to improper handling of
objects in memory. An unauthenticated, remote attacker
can exploit this, via a specially crafted SMB message,
to execute arbitrary code. (CVE-2017-8543)

- An information disclosure vulnerability exists in the
GDI component due to improper handling of objects in
memory. An unauthenticated, remote attacker can exploit
this, by convincing a user to open a specially crafted
document or visit a specially crafted website, to
disclose the contents of memory. (CVE-2017-8552)
