"The remote Windows host is missing a security update. It is,
therefore, affected by multiple vulnerabilities :
- Multiple information disclosure vulnerabilities exist in
the Windows GDI component due to improper handling of
objects in memory. A local attacker can exploit these
vulnerabilities, via a specially crafted application, to
predict memory offsets in a call stack and bypass the
Address Space Layout Randomization (ASLR) feature,
resulting in the disclosure of memory contents.
(CVE-2016-3209, CVE-2016-3262, CVE-2016-3263)
- An elevation of privilege vulnerability exists in the
Windows kernel due to improper handling of objects in
memory. A local attacker can exploit this to elevate
privileges and execute code in kernel mode.
(CVE-2016-3270)
- A remote code execution vulnerability exists in the
Windows GDI component due to improper handling of
objects in memory. An unauthenticated, remote attacker
can exploit this vulnerability by convincing a user to
visit a specially crafted website or open a specially
crafted file, resulting in the execution of arbitrary
code in the context of the current user. (CVE-2016-3393)
- A remote code execution vulnerability exists in the
Windows font library due to improper handling of
embedded fonts. An unauthenticated, remote attacker
can exploit this vulnerability by convincing a user to
visit a specially crafted website or open a specially
crafted document file, resulting in the execution of
arbitrary code in the context of the current user.
(CVE-2016-3396)
- An elevation of privilege vulnerability exists in the
Windows GDI component due to improper handling of
objects in memory. A local attacker can exploit this to
elevate privileges and execute code in kernel mode.
