Summary
======
The package flashplugin before version 11.2.202.616-1 is vulnerable to
multiple issues including but not limited to arbitrary code execution,
JIT spraying mitigation bypass and sandbox restriction bypass.

Resolution
=========
Upgrade to 11.2.202.616-1.

# pacman -Syu "flashplugin>=11.2.202.616-1"

The problems have been fixed upstream in version 11.2.202.616.

Workaround
=========
None.

Description
==========
- CVE-2016-1006 (JIT spraying mitigation bypass)

These updates harden a mitigation against JIT spraying attacks that
could be used to bypass memory layout randomization mitigations.

- CVE-2016-1015 CVE-2016-1019 (arbitrary code execution)

These updates resolve type confusion vulnerabilities that could lead to
code execution.

- CVE-2016-1011 CVE-2016-1013 CVE-2016-1016 CVE-2016-1017 CVE-2016-1031
  (arbitrary code execution)

These updates resolve use-after-free vulnerabilities that could lead to
code execution.

- CVE-2016-1012 CVE-2016-1020 CVE-2016-1021 CVE-2016-1022 CVE-2016-1023
  CVE-2016-1024 CVE-2016-1025 CVE-2016-1026 CVE-2016-1027 CVE-2016-1028
  CVE-2016-1029 CVE-2016-1032 CVE-2016-1033 (arbitrary code execution)

These updates resolve memory corruption vulnerabilities that could lead
to code execution.

- CVE-2016-1018 (arbitrary code execution)

These updates resolve a stack overflow vulnerability that could lead to
code execution.

- CVE-2016-1030 (sandbox restriction bypass)

These updates resolve a security bypass vulnerability.

- CVE-2016-1014 (arbitrary code execution)

These updates resolve a vulnerability in the directory search path used
to find resources that could lead to code execution.

Impact
=====
A remote attacker is able to execute arbitrary code, bypass JIT spraying
mitigations and bypass sandbox restrictions via multiple vectors.
